As someone else was sure to point out on this thread, LT is an incredibly flawed human being, but there is also some good in him, unlike say Ray Lewis, the player most currently compared to him. Lewis pretty much dares you to prove that he had anything to do with the murder he was involved in.
If LT ever had a "sack dance" I am unaware of it.
He had no sack dance that I can remember. No Gastineau, was he.
