In madden 11 there was always one hype up routine it goes a little like this "Who are we? Team name! Who are we? Team name! Are we ready? Are we ready? Win on 3 ..123 win!"
A famous one is "any dogs in the house? whoo whoo whoo whoo! x2"

It'll be nice if they made maybe like 5-8 more different ones just to make it unique because no team uses the same routine really. It's a small addition, nothing major. I just gave it some thought.
