Whats next? High fives get a penalty?
I have a feeling the ban on dunking was because of that one Jimmy Graham dunk that set the goalpost off-kilter... they had to bring out a level and everything. Nothing to do with "showboating", just trying to avoid destruction of stadium hardware...
Can you imagine what would have happened if a dunk happened where the goalpost fell over completely? They'd basically have to play half-field for the rest of the game.
Looks like Jimmy Graham will need to find a new celebration or just hand the ball back to the ref.
