As crazy as it sounds I'll take Breland. Brook doesn't have the right style to exploit Breland's weaknesses and folks forget how well Mark could box when you couldn't crack his chin. And lets not forget that missile of a right hand Breland had. There's always a chance that Brook rocks him and changes the fight but he would have to walk through some fire to do it.
We used to joke about his fragile chin but it was a bit of an exaggeration. Folks remember the losses against Starling and Aaron Davis and how wounded and damaged he looked while being stopped. They don't remember him bouncing Honeyghan and others all over the ring.
Definitely. Aaron Davis stopped Breland but he was busted up badly. They damn near stopped the fight before he turned out the lights.
