I don't think we need a QB. I think Orton will just get better as the team gets used to the system
I just wanted to throw this out since I'm an Arizona Grad. Nick Foles the QB from AZ is really looking good this year and he is only a sophomore and starting his first year this season. He had his team ranked as high as 17th this year and currently is leading the cats against USC. His stats for this year are 2200 yards, 17 TDs, 7 INTs, and a rating of 134. That's pretty good considering the competition he plays against in the Pac-10, 5 of the top 25 teams are in the Pac-10.
Look out for this kid in 2 years as a senior!!!
