It really appears that the Chiefs Management team is working hard at keeping LJ happy. For what it's worth, he's been a happy "camper" thus far. I'm sure Carthon (RB coach has a lot to do with any of LJ's mental successes). If LJ can lead this team, Cassel will be able to do his part without the D in his face.
Case in point:
After practice had ended, Todd pulled Larry Johnson to the side to personally introduce his starting running back to his parents. All four seemed engaged in conversation and were smiling and laughing for about five minutes before Johnson excused himself and stepped away to take questions from the press.
It will go a long way if Waters and LJ can go along with the other veterans that were brought it. As Pioli said, this is year 1 of the Patriots.
Long way to go boys!
