Commentary: The Northwestern Defense (or lack thereof)
by Jonathan Hodges
Obviously
the Northwestern defense (or lack thereof) has been a concern over the
past decade of football. Fortunately during this time period
(approximately the start of the Walker era and going into the
Fitzgerald era of NU football), the offense was good enough
(particularly beginning in 2000) to adequately make up for this lack of
a defense. In fact, the offense was stellar enough to lead NU to
a Big Ten title in 2000, to bowl games in 2000, 2003, and 2005, and to
an overall winning record in 2000 and 2005 (and a .500 record in
2004). The fact, though, is that the Wildcats have achieved this
success DESPITE the defense - not because of it. There is the old
adage that "defense wins championships" and one needs only to look back
at the 1995 and 1996 season when Northwestern fielded a defense that
was more than capable of bringing home the hardware, led by NU
football's current leader, Pat Fitzgerald. Also, NU has produced
a number of quality players during this period - including players who
made it into the NFL including: Bentley, Harris, Castillo, Cofield, and
McGarigle, plus other defensive leaders including Roach and Durr.
And this year's defense has been touted as the most talented unit since
at least 2001 (by Colby himself who confirmed that the talent this year
is the "best he's seen" while at NU) - but even with this talent NU's
defense has looked pedestrian thus far even though it shut out its
first opponent.
Despite this, NU's defense continues to be in the lower tier of
defenses across the nation - something that irks NU football fans and
supporters everywhere who want to see the most success possible for
Wildcat football. The offense has fortunately been stellar and
has more than made up for the defense over this era, but the fact is
that the Wildcats cannot sustain success without a viable
defense. If things don't sync up on offense or if there are
substantial injuries and the offense cannot be relied upon to win every
game, things start to get ugly for NU.
What I don't want this to be about is singling out players.
In fact, I think NU has many stand-up players on defense who have
performed very well over the years and have put their heart and talents
into the game for Northwestern. There are the guys who made it to
the next level who are listed above but also guys who have made a
difference in games - just for one example, Sean Weiber, who forced the
Anthony Thomas fumble in the 2000 Michigan game that allowed NU to pull
off the win. There are plenty more examples and I am not writing
this to diminish the accomplishments of individuals or the success of
the team in recent times. The Walker era at NU is arguably one of
the most consistently positive times in Wildcat football history - and
outside of 1995-1996 has yielded the most consistent winning in a half
century. What this is about is the overarching direction of NU's
defense and the fact that there seems to be no plan for correction of
the recent poor showings from that unit.
To emphasize the issues with the Northwestern defense over this time
period, below is how the Wildcat defense fared in terms of statistics
and how it ranked nationally since 1999, when Coach Walker took over
the program:
Year - Total Defense (rank/# I-A teams) - Scoring Defense (rank)
1999 - 388.0 (81/114) - 27.4 (75)
2000* - 408.1 (89/114) - 30.4 (85)
2001 - 467.6 (107/115) - 34.4 (101)
2002 - 502.3 (116/117) - 41.1 (113)
2003 - 417.3 (88/117) - 25.1 (57)
2004 - 391.0 (68/117) - 28.5 (75)
2005 - 480.4 (117/117) - 33.9 (106)
2006 - 362.5 (85/119) - 26.2 (88)
2007** - 400.5 (79/119) - 15.5 (27)
*Does not include bowl game.
**Through 2 games.
Excluding the 2007 campaign, which only has 2 games completed to date,
the best defensive performance in terms of yardage was 2006, when NU
averaged 362.5 yards of total defense per game, good for 85th in the
nation. In terms of scoring defense, the best number was in 2003
when NU averaged 25.1 points per game on defense (good for 57th).
The trend shows, though, that NU has been at the bottom of the nation
for much of the past 8 years in terms of the defensive - with the BEST
performances falling at just below the 50% range (clearly the worst
performance was in 2005 when NU's total defense was dead last in the
nation).
Obviously the statistics can lie - NU picked up 6 or more wins in the
2000, 2003, 2004, and 2005 seasons - and these stats do not take into
account things like takeaways, points scored by opponents' special
teams or off turnovers, strength of schedule, etc. BUT if NU
gives up the yardage that it has and leads to the points on the board
for its opponents then that is a lot to overcome - something the
offense, special teams, etc. cannot overcome.
Below are some statistics that have a significant impact on the
defensive performance, including turnover margin and sacks (no rank
data is available prior to 2005)) over the same time period as above,
and how NU ranked:
Year Turnover Margin (rank) - Sacks/Game
1999 -0.64 (97/114) - 1.73
2000* +1.09 (6/114) - 2.00
2001 -0.09 (62/115) - 1.54
2002 -0.50 (79/117) - 0.50
2003 -0.15 (72/117) - 1.54
2004 +0.33 (40/117) - 1.92
2005 +0.75 (16/117) - 1.00 (115/117)
2006 -0.58 (97/119) - 1.92 (72/119)
2007** +1.00 (25/119) - 1.00 (84/119)
Turnover margin is a statistic that plays heavily into the outcome of
games - every time NU has a positive turnover margin for the season
since 1999 the 'Cats have achieved at least 6 wins for the
season. The only recent bowl appearance that had a negative
turnover margin was in 2003. Obviously turnover margin also
includes the number of turnovers given up by the offense, but the
overall margin is the best way to evaluate the entire performance of
the team (and compare to the W/L numbers for the season). In
terms of sacks, the best performance by NU was approximately 2 per game
(achieved in 2000, 2004, and 2006) - and when ranking data was
available that put NU squarely in the bottom quartile of the nation.
What Does This Mean?
So, from these statistics one can see that NU's defense has performed
relatively poorly when compared to the rest of the nation since 1999
and doesn't seem to be trending in one direction or the other over
time. The current Defensive Coordinator Greg Colby was brought on
board after the 2001 season (from the 1999 to 2001 seasons, current
Assistant Head Coach Jerry Brown served as the DC), and the between
those two DCs there seems to be no discernible difference in terms of
statistics. Basically, when NU's offense can put lots of points
on the board AND NU comes up with a positive turnover margin - there
can be success (note 2000's very high margin of above +1 per game
coupled with 2 sacks per game plus the high offensive output - which
led to a Big Ten championship). Without the good turnover margin
and/or lots of offensive output, NU is far less successful.
Despite the fact that throughout this time NU coaches, fans, and
opponents have all known the Wildcat defense is weak - despite the
availability of talented players - nothing has really changed. It
was obvious that the Wildcat offense was the preferred unit of Coach
Walker (arguably the mastermind of NU's spread offense and the
sustainer of the point-scoring prowess of the 'Cats - probably dating
back to his days as a fullback at Miami OH), and that the defense was
left to its own devices. With Fitz taking over last year, being
an obviously defensive-minded individual, I fully expected some change
to take place - whether it be assistant coaching changes ( e.g. new DC)
or an increased focus on defense, and while the results of last season
were an improvement - there seems to be NO forward momentum into this
year. It seems that NU has faded back into the same old same old
when it comes to defense - of course 2 games does not a pattern make -
but the 500+ yards yielded to a Nevada team that was held without an
offensive TD in week 1 was not encouraging.
WHY?!?!
1. Lack of an Effective Pass Rush.
This is somewhat surprising given the fact that NU has had the likes of
Harris and Castillo performing the pass rush duties for NU during the
past 8 years or so - and these are guys doing that at the next
level. Looking at NU's sack output (by far the easiest and best
measure of a pass rush), it has been at about 2 sacks/game maximum, and
at worst lower than 1 ( 0.5/game in 2002, arguably NU's worst season
this decade). The past few years (where ranking data is
available) NU is in the bottom quarter of the nation. The fact is
that good defenses get to the QB - a QB who doesn't have time to throw
or find the open receiver is ineffective. If you give ANY QB
enough time he WILL find someone open - no secondary is that
good. This is exactly what NU has allowed for years, thereby
allowing teams to slice up NU's secondary at will, although I will get
to them next...
2. Lack of a Lockdown Corner.
NU hasn't had a "lockdown" cornerback since the mid-90's, although
McManis has shown the tools to be such a player - but he's not there
yet. By lockdown corner I mean a guy who has the tools and, most
importantly, speed to keep up with any WR thrown his way and can use
that speed to make big plays and, most importantly, STOP the big play
by the opponent. Instead, NU is almost forced to use a large
"cushion" on the outside coverage to prevent such big plays - and while
that does work (sometimes) it also opens up a large opportunity for
small-yardage passes at a very high completion rate (since the coverage
is virtually non-existent). There are many examples of teams
eating yardage against NU employing this method... including Nevada
this past week. One may argue NU doesn't need to employ the
cushion any longer and that it is silly to continue, but until the
defense can put pressure on the QB the risk is there for the big play
to erupt and the NU defense to give up even more yards and points.
3. Lack of Backfield Penetration.
One may argue this goes hand in hand with #1, but this has more to do
with stopping the running game. There have been a few years when
NU was horrendous at stopping the running game of opponents - so bad,
in fact, that it has made NU's pass defense look rather good since
teams never needed to throw the ball to be effective. For
instance, take the stats listed below:
2002 Season (Total Defense: 502.3 ypg, 116/117 rank)
Rush Defense: 313.6 ypg (117/117)
Pass Defense: 188.8 ypg (29/117)
Just looking at the pass defense, one may argue - hey it's not that
bad. But, in fact, nobody even bothered to throw against
NU. In 2002, Northwestern was thrown against less than anyone
else in the country - actually the only team close in terms of number
of pass attempts against was Eastern Michigan (281 pass attempts by
opponents total). NU had 239 passes thrown on them. Then
you look at the yards per pass attempt:
Yards per Attempt (against): 9.48 ypa (115/117)
The only teams worse than NU were EMU (9.64) and Syracuse (9.50).
So, basically, if teams had decided to throw against NU they could have
gone even more wild. BUT, when you can run for over 300 yards a
game, who needs to throw the ball?
SO, back to why this happened, basically the D Line was/is ineffective
getting off of blocks. I don't claim to know how to address this,
but as a DL one should be able to get off of the block and at least
direct the play to a waiting LB - or even make the tackle
themselves. Again, I DON'T blame this on the individual players
at all - it is obvious that this is a systemic issue at Northwestern
(one could probably point a finger at the coaching staff here),
especially since some members of those DLines are now in the NFL and
obviously doing a good job there (most notably Cofield and Castillo -
who were actually on the field at the same time while at NU). The
'Cats have had plenty of great linebackers (Roach, McGarigle, Durr,
Bentley) during this time period who have cleaned up in terms of
tackles - unfortunately most of those tackles took place a few yards
away from the LOS - into NU territory. Whether it be how the
technique is taught or the scheme that NU employs, the fact is that
something must be changed to stop teams from running. Look at
Nevada who racked up 192 yards on the ground without even being known
for their running game.
4. Not Changing Anything.
It's been 8 years of a pretty poor showing on the defensive side of the
ball, yet there haven't been any substantial changes on the defensive
side of the ball. ALTHOUGH Northwestern has said it is changing
over to a 3-4 defense (which it has employed from time to time this
year in certain situations), the 'Cats aren't there yet.
Obviously the linebacker position has been solid for NU over the years
(possibly excluding this year, although it still looks like a work in
progress) so it makes sense to try and switch to an LB-heavy strategy,
especially since recruiting for that position is easier for a school
like NU. This year NU has the most talent on the line, so it
makes sense to stick with the 4-3 for now. Hopefully a more
permanent switch to a new scheme will help NU get pressure on the QB
while also stopping the run by sending more/different LBs or even DBs
into the backfield and also allows NU to do different things with the
defenders on the field, BUT that is still yet to be seen.
Obviously a switch takes multiple years given the recruiting and
graduation cycles, but so far there is no evidence of a significant
change in terms of results.
Finally, DC Colby
has been at NU since the 2002 season, and Assistant HC Brown has been
here even longer (he was DC under Walker through 2001 and is definitely
the elder member of the NU coaching staff having been on board as a
Wildcat coach since well before anyone else - including the big 95 and
96 seasons) - and have been kept around despite the shortcomings of the
defense. I'm not calling for their firing - obviously that is up
to Fitz and the NU administration - but if this season passes without
any improvement by the NU defense AND no changes occur in the defensive
coaching staff, one must wonder. It's arguable if Fitz has had
any time to really shape his staff as he sees fit - basically everyone
(except for LB coach Bates, who was most likely brought in by Colby
having previously worked with him) was brought in by Walker - and Fitz
couldn't really blame anyone for last season given the circumstances to
start the year (plus may not have had the authority to make such moves
- especially since he was still settling into the position, having
never even been a coordinator level coach before). SO - I would
personally reserve judgment until this season is over - but I would
hope that as a defensive-minded individual, Fitz would take it upon
himself to demand defensive improvement or else take action to make
that happen.
I would very much like to see NU's defense show off their talent this
year and put this whole discussion to rest - go out there and prove
that 'Cats fans can forget all of those stats listed above and NU can
be a force on defense. Go 'Cats.
