Rockhold look like he was carrying a few injuries into the fight. He certainly has a bad jaw but he has won plenty of decent fights despite it. He has plenty to offer yet.
Sanchez will make money for a while yet as a litmus test for younger fighters. He isn't going to win titles again or beat top fighters but certainly still has enough about him to face up and comers.
Holly Holm I agree with, she looks old in the ring in recent times.
Yes your right he has plenty to offer he could beat 50% of the division but Luke was a champion and a made plenty of cash I can't see him fighting if he has no chance of a title , He is going to get ko'd against any of the top guys so probably best calling it day ,
