Dude, I think it's whatever makes YOU feel better about Manning.
I hope your expectations have been tailored for the first half of the season. Manning will be pretty shaky, as will that offense. It's going to take quite a bit of time to get that unit to sync up.
I have no doubt Manning will get his strength back and some day make it work. But it ain't happening Game 1.
I just want to protect your feelings, that's all.
