When you ask Washington's second-year defensive coordinator Justin Wilcox to describe his base scheme, his answer comes down to "somewhere in between a 4-3 and a 3-4," which means it's got a little bit of everything.
"This day and age, I think all defenses are multiple," he explained.
Wilcox turned in one of nation's best coaching jobs last fall. He took a defense that was among college football's worst in 2011 and made it more than respectable.
Improvement? The Huskies surrendered nearly 100 fewer yards and 12 fewer points per game than they did the previous season under Nick Holt. A unit that had been ranked 106th in the nation in total defense, ranked 31st. A unit that had been ranked 108th in the nation in scoring defense, ranked 39th.
And you could make a case that the Huskies talent was not appreciably better in 2012 than in 2011.
That said, it was far from perfect. The Huskies got pushed around by more physical teams (LSU, 41-3) and were worn out and outrun by up-tempo, spread teams (Oregon, 52-21, and Arizona, 52-17). And they turned in an execrable fourth quarter against Washington State, surrendering 18 points in a shocking overtime defeat.
In the other nine games, they yielded an average of 15.3 points per game.
So when you ask Wilcox what didn't please him, he goes general: "Consistency," he said.
Just like his defensive scheme, that encompasses a lot. For one, the Huskies still need to get bigger and faster and deeper. They have solid talent on defense but they won't yet be mistaken for Alabama or Stanford. To be consistent on defense, starters need to win one-on-one battles and there can't be a significant drop-off when the first-team guy is getting a necessary breather.
The Huskies also seemed to get overwhelmed at times, mentally as well as physically, particularly on the road. Washington played timidly in the first half at LSU, and both Oregon and Arizona had 21-point quarters at home to put those games away in the first half.
With eight starters back and improving depth, as well as a year of seasoning under Wilcox's coaching and schemes, Washington should take another step forward in 2013. It has two big questions: 1. Improving the pass rush, one of the few numbers that was statistically worse in 2012 compared to the previous fall; 2. Replacing cornerback Desmond Trufant, the most significant of two voids in the secondary and the defense as a whole.
The latter won't likely get done. While Trufant's play fell off a bit over the final third of the season due to his playing hurt -- "Dinged," Wilcox called it -- he's still a likely first-round NFL draft pick next week.
"I don't know if we have a guy on our roster who can replace what Desmond Trufant did," Wilcox said. "You try to get guys -- it might be one guy, it might be three guys -- to try and gain the productivity at the position he gave us."
Wilcox did say that cornerback Marcus Peters, who struggled at times opposite Trufant as a redshirt freshman starter, "has flashed." Senior Sean Parker is established at one safety spot, but the competitions at the other two secondary voids remain wide open as the Huskies prepare for their spring game on Saturday, Wilcox said.
As for the pass rush, that starts with junior rush end Josh Shirley, who Wilcox believes played better than was commonly thought among the Huskies fan base.
"He did a good job rushing the passer last year," Wilcox said. "He had six and a half sacks last year but he had the opportunity to have 12 or 13 if he would have finished better."
Shirley also forced six fumbles, tied for first in the conference.
It would be a huge boost if defensive end Hau'oli Jamora is able to come back in the fall after knee injuries killed his past two seasons, but that's not something Wilcox can count on. Jamora looked like a budding star as a true freshman starter in 2010.
"I love the guy. He works and is studying," Wilcox said. "He's doing everything humanly possible to get back ... that would be huge."
The idea, of course, is to "effect the quarterback with a four-man rush." Over-reliance on blitzing and rushing five or six guys is where a defense gets into trouble -- see the 2011 Huskies. It's also not just about sacks. It's about making a quarterback move and adjust and feel uncomfortable.
The challenge of every Pac-12 coordinator is the variety of Pac-12 offenses. There are a wide variety of up-tempo spreads that don't particularly resemble each other -- the Huskies are even going mostly no-huddle this spring -- and then there are pro style offenses such as Oregon State, Stanford and USC. A defensive coordinator in the conference can't scheme -- or recruit -- only one way.
So even with a year under his belt at Washington, expect to see some tweaks from Wilcox next fall.
What's his scheme?
Said Wilcox, "It's identifying what we think we can be good at and catering the scheme as best we can to fit the players were have."
