Leshoure has potential to be, "the guy". He has speed, power and is a very good athlete. I see him being a 1000 yard rusher.
Unfortunaltey the guy is an idiot and I suspect when not causing problems he will be hurt a lot.
We all know Best is a 3rd down or specialty back and Kevin Smith is a tough hard runner but undersized and always hurt. If Leshoure is the answer then the others can fill in on certain situations and all of a sudden our running game is great.
Or, Leshoure plays little, Best plays 2 games and gets hurt and Smith starts out strong but by game 4 he is so beat up the rest of the year is off and on with him.
