Haynes just needs to drop body fat, he probably doesn’t need to cut out much of his weight training. I’ve read blogs of his diet plan, and it seems like he knows what he’s doing when it come to dieting. The dude's went from 330 to 205, and now to 170. I think he’ll be able to make the 170 easily, and he’ll probably look in much better shape.
As for the fight itself, Haynes is a sloppy bastard but he's tough as hell, and Luke is just cool to watch. I think this is gonna be a three round slugfest.
