Poll: Defense most likely to rebound

This week, we've looked at the worst offenses and defenses in the Pac-12 in 2013 and speculated on which is most likely to take a step forward this fall.

We broke things down. Now it's your turn to pick which team you think is headed for better things in 2014. We'll do defense today and offense on Friday.

Here's the North Division defensive breakdown. And here's the South.

There is one problem. Our poll tool only allows for five choices, so obviously one team must be eliminated. So goodbye Arizona State, which played pretty good defense last fall and lost nine starters. While there is no certainty the Sun Devils won't be better on defense in 2014, the odds are more against it than the other five teams.

And, no, you can't vote for Oregon, Ducks fans.

Obviously, California almost can't help but improve, particularly if its luck with injuries is a little better. Colorado has the most returning starters.

Utah has a strong defensive tradition, while Oregon State seems like a unit that alternates good years with bad -- with a good year perhaps approaching. Like Oregon State, Washington State loses its best player from 2013 to the NFL, but it has a sneaky good front seven coming back.

So what's your take: Which defense toughens up the most in 2014?
