Smith was geared to have one of his best years ever this year, but he also was on the best team in the league. Great WR's, great run, great D. Smith had it all in his favor.
Kinda why I'm interested to see how he does elsewhere. I think he's obviously better than Cassel, and would have been better than Mark Sanchez (or Nick Foles), but I'm hesitant to call him "good".
Regardless of all that, it speaks for itself that he's a player very serious about improving his game and hungry to win. He seems like he eats, sleeps, and breathes football. Something most mediocre QB's don't have going on.
