Jones is a monster at 205. If he makes it past Hendo and Machida again - then a move to heavyweight is the next logical step.
Looks exactly how I'd expect a guy to look at 6'4" and ~100kg. He's not ridiculously outside the weight limit, and to my knowledge he's never struggled to make weight. He's still got some time at LHW before he makes the move up, I think.
Hence " Bones " , his legs have gotten bigger since his early MMA days , between fights now Jones looks like a genuine HW
