"Gleison is a tough opponent. He's huge, he's the biggest guy in the division. It's not an easy fight, but that's what I want. I thrive off of that stuff. He hits hard. He's a big guy, but I think he's gotten better controlling his weight cut. He hasn't gassed out recently like he has in the past. I don't care about getting tired myself. I'm ready to leave it all in there."

Larry Pepe of Pro MMA Radio caught up with Jim Miller as he readies himself to take on the biggest opponent of his career, literally speaking, in Gleison Tibau tonight at UFC Fight Night 22. Miller is well aware of the size disadvantage he has, but asserts that it's fueling his motivation. Will the size difference between these two lightweights be too much for Miller to overcome? Let's get some last-minute thoughts on this match up.
