Matt Barkley isn't the consensus No. 1 quarterback prospect for the 2013 NFL draft, but if you're looking for the most NFL-ready passer, Barkley gets my vote.
The USC offense is straight out of the NFL thanks to Lane Kiffin's methodology. Barkley has spent four years in a scheme that will be very similar to what he's asked to do in the NFL, and just like Andy Dalton last season and Andrew Luck this year, we've seen where that makes a huge difference for a rookie quarterback who is asked to start right away.
Barkley has flaws, to be sure. He's small (6'1 1/2", 200 lbs.), and he plays in a system that's dominated by All-American players. Extrapolating Barkley from that scheme and projecting him to the NFL is tough, because chances are, his wide receivers at USC are better than the duo he'll throw to in his first NFL season.
What can be learned about Barkley is that he's smart enough to run a pro system and be highly productive doing it. Barkley stands above the rest as a first-year prospect who can produce from the opening snap.
