"They can't do that!"

[bainsey]

I'm looking for a parallel here.

If you saw the end of the Giants/Bucs NFL game yesterday, you saw the Giants in a "victory formation," but the Bucs opted to pound the line and go for the ball. The Giants were pretty upset about that, even though it's completely within the rules, it's something you "just don't do," according to Coach Coughlin.

(Personally, I think Coughlin needs to review Herm Edwards' famous line.)

Does anyone have an experience along this line where a coach thought the opposing team was doing something wrong, yet it was well within the rules, and possibly innovative?
