That anti-celebration rules are the best rules in the book.
I used to hate the celebrations, and I still don't like Chad Johnson and TO "Bojanglin' " (Jason Whitlock) in the end zone. But SA's celebration was pretty tame by comparison. And really, it just makes those guys look like idiots when they lose. If they want to make fools out of themselves, then let 'em.
I agree with you about the tackle celebrations, especially by ST players.
