I'm a little biased, but I'm picking a dark horse for the Pac Ten.
Arizona is returning 10 offensive starters, including Nick Foles who threw for almost 2500 yards and 19 TD's and showed remarkable poise as a freshman.
If the defense can fill some holes and if they can overcome that embarrassing Holiday Bowl shut out to Nebraska, they have a real shot at the Rose bowl.
They are certainly hungry enough.
Arizona is a team to watch. When Iowa played them last year they had a great secondary and at the time Grigsby was the second leading rusher in the nation. They will play Sept 18 in Arizona. Should be a very good game. Iowa will have one of the top defenses in the country, Nick Foles may have some trouble moving the ball against them.
Oregon should be interesting this year. Both of their backups are familiar with the system, but have limited game experiance. Nate Costa being out w/surgeries (2 years ago?) and Darron Thomas a sophmore.
