I'm not totally convinced that starting AJ will lead to more interceptions. We all were saying the exact same thing about Greg two years ago.
Coach Mac's passing game prominently features a lot of high-percentage, low-risk stuff, and we've seen low interception totals from starting QBs for three seasons now. John Parker threw 13 INTs in 2006, 12 in 2007 and was down to either 8 or 9 in 2008. Greg has thrown 9 in two seasons as a full-time starter. We're a risk management offense and I don't think we'll see a high interception count from a starting QB as long as Coach Mac is around. With AJ's apparent arm strength, I'm sure we'll look to stretch the field a little more often, but I don't necessarily see that resulting in more picks. I see his big arm leading to overthrows on the deep stuff, and when you go downfield it's the underthrown passes that are more susceptible to interception.
I'm not saying that AJ will go out next season and only toss 3 or 4 picks, but I don't think he'll throw 13 or 14, either. I think 6 or 7 is a realistic number. Now, being a first-year starter I'm sure we'll see completion percentage drop a bit. Hard for a first-year guy to complete 70% of his throws.
