Henderson can indeed be a good, above average RB....His ONLY issue is the injury thing, but even if a guy has been injury prone in the past doesn't mean he can't rip off a long healthy streak.....I remember the hammy issues Bruce had early on, couldn't stay on the field, he got good and never looked back....Now it may not be the same type injuries that Darrel has had, but I see no reason he can't get good and stay up.
Even if that does work out, I'd like to see a different body type incorporated into their game time mix. To me it would make sense when they pick up a guy he would have a bigger body, unless they have visions of an AD bulldozing....lol....
