I think the he started to look the part more in the second half of the season. I was just looking at his splits to see if theres anything in the numbers that supports that:
weeks 1-10 5 games played
51 comp / 110 att (46%), 600 yd pa, 2 td / 5 int, 65 yd rsh, 1 td
weeks 11-17 7 games played
120 comp / 184 att (65%), 1311 yd pa, 7td / 7 int, 195 yd rsh, 2 td
Those 2nd half season numbers were pretty respectble, extrapolated over a full season (I know its always a dangerous thing to do) you'd get somewhere around 3000 yd, 16 td, 16 int, 450 rsh yd, 4 rsh td; good enough for somewhe around qb 12 - 15 in most scoring formats last season thanks to his rushing stats (with all the injuries and turnover at qb last season he still ended up qb 20).
I think he'll be given this year to prove he can manage games and not turn the ball over as much, fantasy wise he looks like a no 2 QB with the odd spot start but with some upside due to his rushing stats and strong arm.
Besides it'll be interesting to see how many points he'll gain by Troy Williamson no longer dropping long bombs that would have been td's
