UFC 137 was bizarre weeks before the card even started, with no-shows at press conferences, rearranging bouts, and a weighin that featured one fighter who didn't make weight and another one who learned the value of a good headbutt. But who stood out once the actual fights began?
No. 1 star -- Nick Diaz: Heading into UFC 137, Diaz promised that he always shows up for a fight. He came through, beating up on B.J. Penn so badly that Penn said that he would walk away from his 10-year MMA career. Then, Diaz launched into a string of expletives to call out Georges St. Pierre. It was not as smooth as Chael Sonnen's heel act, but it was more effective. Diaz will fight GSP on Super Bowl weekend.
No. 2 star -- Roy Nelson: Showing off an improved physique, he withstood the best that Mirko "Cro Cop" Filipovic had, and then took out the MMA legend in the third round. The win halted a two-fight losing skid.
No. 3 star -- Donald Cerrone: Speaking of streaks, Cerrone extended his winning streak to six with submission of Dennis Siver. He used his kickboxing prowess to knock Siver down, then smartly slapped on a rear naked choke to finish the fight. Next, he'll fight Nate Diaz at UFC 141, giving Cerrone his fifth fight in a year.
