What's better than beating your opponent? Beating your opponent then rubbing their face in it.
I've always loved celebrations in football. I sabotaged many a NCAA Football game on PS2 by insisting my players excessively celebrate every touchdown (R2+X amirite?!, please excuse the lame gamecube controls in the linked video), and the mid-2000s were the golden age for football celebrations. Guys like Terrell Owens and Chad Johnson basically forced the NFL to crack down on how far a player could go in their celebration, and college football, sadly, soon followed suit.
These days if a player so much as gives the opposition a second glance it seems like he'll get flagged.
