While I would have much rather seen Mac Danzig in this fight, Rocha stepping in on late notice against Cerrone could be pretty entertaining. Rocha isn't exactly known for his striking prowess, so if Cerrone can keep this fight standing fans could be treated to a nice stoppage.
Unfortunately for Rocha, Cerrone is just too well rounded for someone who only started fighting two years ago. Regardless of where the fight ends up, I like Cerrone to hold a comfortable advantage. Unless Cerrone foolishly abandons his gameplan he should make this his fourth-straight win, setting him up for tougher opponents moving forward in his UFC career.
My pick: Cerrone via TKO
