Don't mind if I do...
First off the USC QB thing isn't BS, its overwhelming evidence that QBs from that school have not faired well in the NFL. If 1's a blip and 2's a trend, then what's 6?
Barkley has not done well in 'big' games. This month vs. Oregon was the first big game he's won in his career.
But perhaps the biggest problem with Barkley is his attitude; he has an attitude similar to Leinart and Sanchez; something Palmer didn't have which is why he did "ok". Very similar to Clausen's attitude which is why he didn't pan out in Carolina. The guy is a pretty boy prima donna that will surely rub teammates the wrong way. Take a look at this article which does a pretty good job of breaking down some of the boneheaded **** he's said "

"Oh but he has all the tools!!!" Listen, being a successful QB in the NFL is about 70% intangibles, that's why Pennington was so successful with such pitiful arm strength and average athleticism. People have to want to follow you in to battle. No one will want to follow a ******** like Barkley into battle, sorry. It's a running theme with these USC QB's...a pampered college lifestyle, a strong belief that their **** doesn't stink, and a rough time coming to the realization upon entering the NFL that their **** does in fact stink.
I know you'll try to say this is a weak argument, but the evidence is overwhelming. **** Matt Barkley, he's a ***** *** pampered California boy and he is not a leader. In the NFL you need LEADERS!
