Yes, he had the balls to fight big guys with less talent, less ranking, and less overall fighting ability. Big whoop. Fighting a squash match doesn't take balls. It took more balls to stand with Mirko or dive into Nogs guard. Fedor wasn't "small". Arlovski weighed in at seven pounds more than Fedor. This is some sort of huge differential? Guys like Timmeh, Zulu etc may be bigger, but their size brings significant disadvantages. They're generally awkward, lack athleticism and speed, etc or in the case of Zulu is just a huge fatass. It's not just an advantage, it's a double edged sword. Actually, being a fatass is a huge disadvantage.
The latter part of your post is thinly veiled Jones hate. He smashed Chael, yet somehow he didn't have the "balls" to fight him. And this is the first I heard that he ducked Chael to prepare for Cormier, who hadn't even fought at 205 yet. Do you think before posting?
He could move up to HW and you'd say he's ducking Gus.
