Rivera is playing serious mind games. Perhaps they are getting to Bisping, I am not sure. I like Rivera as a fighter, he is very exciting to watch and has tons of heart. I think when they get in the cage together Saturday night Bisping is going to pick him a part with standup and win the grond battle should it end up here. Unless Bisping gets caught clean and finished he will win this fight with ease and I think a 3rd round finish, TKO.
