It's been over a year since Jon Jones won the UFC light heavyweight championship from Mauricio Rua and began this long journey to a showdown against his former teammate and training partner, Rashad Evans.

Both have won multiple fights in the meantime. "Bones" defended his title twice by submitting both Quinton Jackson and Lyoto Machida while "Suga" ran through Tito Ortiz and Phil Davis. All just to set up tonight's (Sat., April 21, 2012) mega main event for UFC 145 at the Philips Arena in Atlanta, Georgia.

Jones is a big favorite, around 4-to-1, actually, but Evans has done his best to convince fans he's got far more to offer than than the oddsmakers are giving him credit for.

But how can we determine as much? Well, UFC cameras went deep behind-the-scenes to get a look at how both men are preparing for the fight of their lives with a three-part "Primetime" series that aired on FX.
