What do you think?
I wish that big superfights could be 15-rounds again. It would provide for more definitive wins. Too many 6-6 or 7-5 rounds for either fighter in close fights. Most fights are fine at 12 rounds, but if you have a fight with like the RING Title on the line, or at least three alphabet main titles on the line, do 15. Make it like the superbowl of boxing.
For safety, make sure only the best refs do the 15-round bouts.
