Weirdly wonderful match up- Has it been done? Koichi would have some official "size" on Kostya but really Wajima actually weighed 154lbs. Kostya truly weighed about 150 odd lbs himself. I believe for Humasho he came in at 154-157lbs? Tell me what you all think. (@roughdiamond I have seen you post a bit about the frog what do you think?)
I like Koysta in this one. He gives up some size but he is the stronger/heavier puncher and Koichi has five Ko losses and could most definitely be hurt by that right hand.
Kostya was about 150-155lbs. I don’t believe size is a problem he was also a very strong fighter he’s benched 225lbs for over ten reps according to a few accounts. He also has a very high clean and jerk we can assume he is at the very least the stronger man in the ring.
