Where is AP going on draft boards?

I have the second pick and I can't decide what direction I want to go with it. I love AP, but I'm a little wary about RB's getting up there in age. When they drop off it tends to happen suddenly. I feel like the 1st round running back talent is pretty deep this year and there are a lot of viable choices at the 2 spot but I can't seem to pull myself away from wanting Peterson.

I haven't kept up with offseason football like I should have, but is Peterson looking as physically able as in the past? Is his age going to be a factor?
