I hope that we start the best player. ...
Since we weren't at Fall camp, we can't say who was best there, but based on stats from last year, it would be hard to say that the choice of Vick wasn't reasonable:
Passing
Vick 94-160-4, for 1156, 8 TDs 7.23 yds/attempt, QBR 130.9
Sprague 98-202-5 1236 yards, 3 TDs, 6.12 yds/attempt QBR 99.9
(Windham 10-13-0 82 yards, 6.31 yds/attemp, QBR 129.9)
Rushing
Vick 82-390 4.8/carry 1 TD
Sprague 65-264 4.1/carry 3 TDs
(Windham 6-20, 3.3/carry)
I presume that after a few games we'll all have opinions about who should be starting, but for now Vick seems like a good choice.
