Yeah I still don't see Bisping being able to stay away from Hendo for an entire fight. And I think that's really his only chance of getting the W; staying away from him.
The jury is still out on TRT-less Vitor. I'm sure he still has power, as he had The Chris on his heels for a few seconds in that fight before Weidman did a good job of covering up and letting Vitor tee off on some forearms before taking him down and demonstrating Vitor's amazing lack of groundgame.
But I don't think Vitor is all-around as strong as he was on TRT, and clearly not as big.
Still, if Bisping chose to go toe-to-toe with him, I think Bisping goes down hard again. He'd have to employ a wrestling-heavy attack and wear him out.
