Obviously the player would have to have some kind of natural ability for the position but at the end of the day, the idea isn't so crazy. Take a guy like Santana Moss for example.. with proper coaching at 5'10 200 pounds, why couldn't he have excelled at the RB position? He'd have elite speed, elusive moves... to me would probably be a 1000 yard rusher. Obviously when you draft a WR, your in need at that position and it would make absolutely no sense to convert the guy you just drafted to a different position. But thinking outside of the box, perhaps it's late in the draft, you see somebody on the board that has all-around talent, just doesn't do one thing great... a Hester-type player and he's been a WR in college, why not take a gamble? Take a guy like Jacoby Jones at 6'2, 210... out of college, help breaking down schemes for him... I think he'd be lethal out of the backfield, big, extremely fast, elusive.. Has this ever been done before successfully?
this guy piled up some points for me back in the day
Even smurf Sproles is 5'6" and 181. 5'6 vs. 5'9 is pretty significant for basically the same weight.
