How Would Boxing Be Today With 15 Round Fights?

talk about it in general, also what guys would or wouldnt benefit from it, and some fights the last few years that may have played out differently. With that being said, we dont know for sure if it wouldve played it differently or not due to guys would fight a lil different if they knew they had to go 3 more full rounds possibly. Pac & Floyd would probably still be rated as the top 2 since they both have great stamina, although Pac did look a lil winded at the end of the JMM fights but maybe that was the cramps.........lol
