Kosta both technically excellent. But JMM probably not going to put Kosta on the back foot enough and ruff house enough in close and Kos has the bigger punch.
I don’t like this match for Marquez. Even at 135, Marquez was giving away size, and some speed. At 140 vs. a career 140 guy as good/great as Tszyu, I don’t think it happens for Marquez. He’s tough enough and skilled enough to have some success, win some rounds, but overall he loses a clear-cut decision.
If Pac and Floyd can floor Marquez I think Tszyu would go a step further and stop him, JMM has neither the speed or power to keep Tszyu off him
