I don't see how Hamill can win this one. Thiago's wrestling is good enough to avoid the takedowns - he will control where the fight goes.
Thiago by KO round 2.
Hamill was decent maybe 5 years ago. He isn't decent now. His shot is too slow. The game surpassed his game.
Thiago 1st round TKO or Hamill hangs in tough and gets his head beat in for 3.
