Greene shouldn't have to explain himself ... this is competition. It's [I]fun[/I] competition. I don't care who the player is -- T.O., OchoCinco, L.T. -- whatever your reputation ... when you celebrate a touchdown, it's a form of talking trash. No harm in it ... but nobody (player, team, fans) ought to be mad about it if it's mimicked.
If Chargers fans are going to be mad at Shonn Greene, then they ought to be mad at L.T. as well. If it isn't "right" in one case, it isn't "right" in another. Besides, L.T. isn't going to get upset about something as trivial as that.
