Next ASU Opponent: Arizona

Here is a look at ASU’s next defensive opponent the Arizona Wildcats comparing how the team has done so far this year versus the results from all of 2013.

Points allowed per game……2014—24.6…….…..2013—24.2
Yards allowed per game.……2014—440……..……2013—-401
Turnovers per game…….……2014—-2.0….………2013—-1.7
Giving up red zone TDs…….2014—57%…………2013—-67%
3rd down conversion rate….2014—40%………..2013—-39%
Completions % allowed…….2014—65%………..2013—-59%
Havoc Rate……………………..2014—19.7%………2013—16.7%
Sacks per game..……………..2014—2.7…….….…2013—1.4

The big difference between this year’s Arizona defense compared to last year is that this year’s squad seems to be pressuring opponents a little more than the squad last year based on the increased number of sacks per game and the increase in its Havoc Rate. It is also a bit stingier in the red zone compared to 2013. However, the 2014 Wildcat defense is giving up almost 40 yards more per game this year, along with allowing a 6 percent increase in pass completions. The most important category, which is the points allowed is pretty much the same for both years.
