Extrapolations are just estimates of course, I think had Keon stayed healthy he would have exceeded 700 yards and tacked on 1-2 TD's in a middle range projection. Of course he could go below or above that it's all just a guess. Of course Keon is going to have to learn to overcome adversity and improve upon his rookie season. By all accounts he's a hard worker with a high football IQ, so the effort will be there.
