The biggest problem is that you have no idea who's gonna draft them yet. I mean, I think Eli Manning could be great, but if he gets drafted by Arizona for example, my enthusiasm would be a bit tampered. Kevin Jones and Chris Perry have the potential to be great NFL backs, but if they go early in the draft, and some guy gets drafted round 2-3 (Darren Sproles, the Mighty Mite?) to a strong team, he could blow up.
That said, I like Manning, Fitzgerald, Jones, and Mike Williams
