I actually think right now is the best time to find out how healthy he is as a starter, actually. It's week one, so even if Peyton doesn't play the way you want him to you've got plenty of time to figure out your starting QB for the following weeks. I think he's better than the other two QBS you have anyway. You drafted him knowing you'd be taking a slight risk, it'd be kind of silly if you didn't actually take the risk, so take it.
Roll with Peyton!
