The most indelible image I have of him was when he broke Theismann’s leg. The way he waved for Washington medical staff to help Theismann showed me he was concerned for his competition. Can’t ask for more than that on the field of top-knotch sport.
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.
