My only real concern with Walker so far is his desire to bounce to the outside too frequently. Sometimes, the play is just dead, and it's ok to take the no gain. I don't want to see him trying to make every run into a home run and lose 5 in those situations.
Again, just a minor concern. He sort of reminds me of early Reggie Bush like that, and teams will key in on that.
Otherwise, so far, he has all the traits you want in a franchise back.
