He's only had 1 bad MW fight, so i think it would be a good move for him. If he loses to Machida, he'll have a better chance of fighting Silva than he does Jones.
He looks far more ferocious at LHW. He can make 185 but it's clearly not his optimum weight. I'd say almost every performance at 205 has been better than his fights at 185 since he moved up to KO Wand (excluding Bisping I suppose).
I think the cut has a little too much detriment on his cardio these days. He's looked better at 205
Yeah. Plus, he isn't getting any younger and most will say cutting weight gets harder with age.
No. He has never looked as dominant at mw. Even in PRIDE he looked lackluster at 183. He had two close fights with Misaki going 1-1. He looked terrible against Shields and has said he doesn't want to cut down unless it's for a title.
