I don't even see why anyone would plan "long-term" at RB. Unless you can get a transcendent talent, what's the point? RBs are exposed to so many hits that, in all likelihood, your RB trajectory is going to change a multitude of times over any long haul. Kinda ironically, I'd rather just do what the Jets did: target guys that you like in the 2nd-4th round, and grab one of them every couple of years (move up if you have to). Always have a relatively dynamic young talent, and rarely, if ever, sign any of them to a second contract.
