JRM needs to gain the weight and be able to prove he still has his speed and quickness. If he gains the weight now and runs a 4.75 at the combine, he's screwed himself. He needs to be 235-240 and still move like he does to have a chance to get drafted in the 3-5th rounds. NFL team wont take a chance on him hoping he can gain the weight and not slow down. Too many other guys that size already that they know what their speed is.
Kamara just doesn't seem anywhere near physical enough to play in the NFL right now. Outrunning some college guys vs NFl guys are two different worlds.
