I love the idea of TreVeyon Henderson... but not if he's going to get hit in the backfield most of the time.
He's a great back, with patience to find a seam, followed by a great burst. I don't know if I've ever seen a guy that can change gears and break off a long run like him.
His history of durability is a problem, though.
If there's actually a hole where where the hole is supposed to be, Najee is just fine. Problem is, that's very rare in our offense.
Warren is a strong little speed back that hits the hole, or lack thereof, really quickly and sometimes can break through, but often gets arm tackled and tossed down like a rag doll. I'm not sure he could ever be a 20 carry guy, but we don't really know because it's never been tried.
If we're gonna let Najee go, and Henderson is there for our third pick... hell yes, get a real OL coach, fix the blocking schemes, 1a and 1b between him and Warren, and see what happens.
