Poll: Which Pac-12 defense rebounds?

On Tuesday, we looked at the five worst defenses in the Pac-12 in 2012: UCLA, California, Washington State, Arizona and Colorado.

The issue was not pointing out past badness but considered the potential for 2013 improvement. That included returning starters, defensive line starters back, star power and the biggest personnel loss.

Here's our chart:

We've already offered our take: While all five teams have the potential to improve, perhaps significantly, the most likely to make a big jump is Arizona, due to 11 returning starters.

But what's your take?

Colorado might be the pick just because it will be difficult to surrender 46 points per game again.

California has a solid recent track record on defense, though that was with a 3-4 scheme under Clancy Pendergast, who's now running USC's defense. The Bears' 2012 performance might rate as an anomaly. There is plenty of returning talent.

UCLA also has some strong returning talent, led by Barr and MLB Eric Kendricks. While the secondary is being entirely rebuilt, the young players slated to step up might be more physically talented than those who preceded them.

Washington State is replacing four-year sack leader Travis Long, but it's got a lot of guys back from a unit that will be far more seasoned this fall.
