Saw this link & I remember watching this guy:
Inside Scouting Report on Redskins UFA: LSU RB Keiland Williams - Hogs Haven
He seems to run straight up too much as I recall, doesn't lower his frame enough. I do think he has a chance to make it as the #3 rb due to his hands & if he can play spec. teams. I see Parker as the odd man out if they like this kid's work on teams & pass catching, even if Parker is the better runner.
