Kayla by lopsided UD. She is tough enough to eat a few punches as she closes the distance, then will secure the takedown and dominate from top position while Cris spends the majority of the fight trying to get back to her feet only to be taken down again.
Unfortunately, I don't think we will see this fight. Cris has a history of talking bullshit that never comes to fruition. Before this Harrison idea she was spouting off about a Bellator-UFC cross-promotion rematch between her and Nunes. Yeah, if Dana wouldn't do it for Fedor he is going to do that for Cyborg?!? Nah. Coker sounds delusional in his praise for Cyborg but he isn't dumb. I'm sure he knows Harrison is a bad matchup for Cris, so why would he take the chance of tarnishing the aura he is trying to promote by risking a loss to a fighter not under his banner?
I hope this comes to fruition, I just do see it happening.
