In their prime, I'd go with Henderson. Now, even though Belfort hasn't fought since the trt ban, I still think he gas a bit more in the tank. Henderson still has a loaded right, but against a lefty, I think he's going to struggle. I'm going with Belfort ko first round. Kind of sad seeing these pioneers just withered away. Hope it's better than the Mark Kerr/Oleg Taktarov
