A few months ago I was convinced that LMJ would be a nice special teams and RB 2/3/4 NFL guy. Now, not so much... Seems to be a trend in the NFL to smaller/quicker backs. LMJ fits the bill with speed and strength (he's a beast in the weight room at UO).
I know there are variables, but in the right system, I don't know why LMJ couldn't compete with:
Westbrook 5-8, 200
Dunn 5-9, 180
MJD 5-7, 205
Sproles 5-6, 180
Tomlinson, Peterson, Johnson...and so on...
Here's an interesting read that relates to the change in NFL game and how smaller, quicker RB's who are dual threat and can run routes like WR's, could be in high demand:
