Former UFC Heavyweight Champion Frank Mir (14-5) will try to continue his climb back up the 265-pound mountain when he takes on Ultimate Fighter (TUF) 10 Champion Roy Nelson (15-5) at UFC 130: "Rampage vs. Hamill" from the MGM Grand Garden Arena on May 28 in Las Vegas, Nevada.
Mir has been labeled as the "favorite" in this titanic tilt -- but not by much.
Most oddsmakers have him at -135 while his rotund rival rolls in at +105 as the underdog. They own similar records and "Big Country" even holds a 2003 Grappler's Quest win over Mir but as far as mixed martial arts is concerned, Nelson has faced very few "elite" heavyweights during his stint as a Zuffa employee.
He's also coming off a lopsided unanimous decision loss to Junior dos Santos back in August while Mir rebounded from his drubbing by Shane Carwin to Cro-Cock Mirko Filipovic last September.
Are the oddsmakers calling it like they see it? Or playing it safe? Take a look at how these two heavyweights stack up and decide for yourself.
