The dude is a 1st round draft pick, we need to get him out on the field. He's had exactly 10 rushing attempts in 2 games. I know Willie is the unquestioned starter on this team and that's as it should be. He's earned it and he's playing very well so far this year. He's got 53 carries so far to Rashard's 10?
If we brought this guy in to spell Willie then why not get him some significant playing time. Perhaps he's still a bit in the dog house with the fumbles from preseason or maybe the game plan just hasn't presented itself with time for him to get on the field. Either way this kid can be something special but he needs experience. Why not stick him in for a series or 2 each week and let's watch him start making an impact. Maybe he just gets 10 touches a game so far, or 15. Sometimes more or less depending on how the game unfolds.
Personally I don't think he's real suited to be out there returning kicks anyways but atleast he's on the field doing something. Yeah I know we're heading into week 3 but if God forbid something would happen to force Willie to the sidelines then it would help to have your star backup atleast know which direction the first down marker is in
