Nunn wins. Winky has more longevity, and has been more consistent in his career, but Nunn in his short prime was one of the most talented fighters the middleweight division ever saw. Its a bad style matchup for Winky. He doesnt have the power that Toney had to wear Nunn down, and from the outside he doesnt stand a chance of outboxing Nunn. Plus Micheal was physically strong as hell, he's one of the few guys who I could actually see pushing Wright back. Nunn wins a very clear UD. BTW- Nunn would have wiped his ass with Taylor.
I would go with Nunnfdgdssddw fdgdssddw In a stinkfest because of Nunn. Like X, said, it is a bad style match up. Nunn's speed of foot and hand would help him out. I think Nunn gets the call from the judges in a fight fans will debate.
I think Winky's style bears similarities to Starling and (especially) Rocchigiani - though whether that's an argument for or against Winky depends on your PoV. Either way, I think we get a somewhat ugly distance fight that ends with a lot of dispute over whether the decision should go to the busier fighter (Nunn) or perhaps the more accurate one (Winky).
