Why not get the best of both worlds?
I always target a RB who will catch 4-8 balls a game for that slot. (Westbrook, Faulk, Staley, Barlow, James). Sure Henry looks bad there, but only because he rarely is targeted to catch balls out of the backfield. Plug in any one of these guys, and unless you have a top 5 WR, you will get not only better, but more consistent production.
