He looked solid last night.
I still think he has a Matt Schaub ceiling, though and would be ideally suited for a west-coast scheme.
If the Chiefs take him and surround him with plus talent, they can win with him. But they're not going to be able to take him and surround him with mediocre talent that he makes better (i.e. the Rodgers, Manning, Brady, Brees class).
I'd still prefer Smith because I think he has more upside. Wilson and Bray might have more upside as well. That said, I could ultimately live with Barkley because I just can't see him being a bad quarterback. We'd have a guy that doesn't take anything off the table for the next decade and as he matures, because of his background, he could even be one of those 'pressure' players that steps up when needed.
Not my favorite choice, but an acceptable one.
If you can't draw a crowd, draw dicks on the wall.
