For the first half of Chael Sonnen’s career it didn’t appear as though the hard-nosed wrestler was likely to have much of an impact on the MMA landscape. His record was mediocre and he had no real signature wins to speak of. However, for the past five years Sonnen has been a major player, earning numerous title-shots and emerging as one of the UFC’s most recognizable faces based on his work inside the Octagon in addition to his role as a member of the FOX broadcast team. This weekend the 28-13-1 Sonnen is set to collide with Rashad Evans (18-3-1) in co-headlining action at UFC 167 where the 36-year old will have an opportunity to add one more high-profile win to his resume.
