The UFC brings fans a prime cut of its well seasoned roster with UFC 121: Lesnar vs. Velasquez tomorrow night. The card is loaded not only with top class fighters but also a slew of superstars. The main event features heavyweight champ Brock Lesnar (5-1) and Cain Velasquez (8-0), and the under card is stacked with men worthy of supporting such a magnificent event as a fight for the most prestigious title in MMA: the UFC Heavyweight Championship of the World. “The Hitman” Martin Kampmann (17-3) faces former Strikeforce middleweight king Jake Shields (25-4-1) in a welterweight tilt, TUF Season 10 stand-out “The Hybrid” Brendan Schaub (5-1) and “Napao” Gabriel Gonzaga (11-5) battle to remain relevant in the hunt for the belt Cain and Brock will dispute, and The Ultimate Fighter Season 3 contestant “The Hammer” Matt Hamill (8-2) will battle his former coach, the ultra-polarizing former UFC middleweight/light heavyweight champ “The Huntington Beach Bad Boy” Tito Ortiz (15-7-1). In a situation similar to Gonzaga’s bout with Brendan Schaub, “The Nightmare” Diego Sanchez (21-4) joins Brazilian sensation Paulo Thiago (9-2) in the Octagon. The bout is similar in the fact that Gonzaga and Sanchez both were once title contenders but never had the completed skill set needed to remain at the top or tear a belt from the grasp of the respective champions they would face. Meanwhile, Thiago and Schaub both rode into the UFC on a hype train that somehow managed to get off the tracks. Thiago came in to be a tomato can for “Kos” Josh Koscheck (15-4) and promptly knocked him out, igniting sparks of phenom-hood, only to be driven back into mediocrity by losses to Martin Kampmann and Jon Fitch (22-3).
