Nothing in boxing irritates me more than the punch number system. Cus D'Amato invented that at some point, or so the story goes, and when Tyson became champ everybody seemed to go with it. You could not go into a gym for the longest time without hearing somebody blaring numbers like a marching cadence.
The second most irritating thing in boxing also comes from the Tyson era. This would be the "move your head after you punch" crap. To this day, in most any gym, you can see the fruits of that abortion. Somebody throws four punches with no shoulder turn or weight shift, etc... then bobs their head side to side. Moving no more than an inch or two in either direction.
