Gus won all his fights in LHW by being elusive, like Machida, but without relying so much (to the point of irritation) on counter-attacking.
I suppose this trait would carry over in HW, though unless he gained weight and became a lot stronger I don't see how he would overcome the strength difference against all those top tier 240 -260 pound guys...
He lacks power and killer instinct.

i think he could fo well, providing he could stop guys walking through his shots and tagging him.
He'd do.ok, better at 205 though.

I dont think he lacks power, he just didnt hit jones on the button, he's ko'ed guys before.
I think he'll be HW before the end of his career
