If these guys can go the distance with Joe, Lacy should have no problem. And I expect Joe to box Lacy from the outside all night long, and not going for the KO by punching witha puncher.
I think the great gardenweasel has a very good point about Lacy getting in trouble for hitting to the back of the head. Look at the way Lacy has finished his last two fights, he finished Reid and Pemb with wide shots to the side/back of the head. Reid said after the fight that Lacy kept hitting him "cuffing shots" behind the ear and he was absolutely right. These shots are technically legal and will be allowed here in the states, BUT this fight is whole different animal. Like gw said, Lacy could get dq'd. IMO if he hits Calzaghe like he was hitting Reid there's a good chance the ref will warn him, take points, and dq him. There's no doubt in mind that Calzaghe's camp will warn the ref about Lacy's tactics and he will be forced to respond considering the location and promotion of the fight.
I feel the above could play a huge role in this fight, but I'll also give my take on the fight assuming the ref stays out of it.
Calzaghe throws the straighter, sharper punches of the two, he has better boxing skills, he's a slick southpaw with a 3" height advantage and he's never been beat...not even close, and he's fighting in his backyard with Warren behind him.
And those aren't the only positives for Calzaghe, Lacy is very wide with his punches and leaves himself open on a regular basis, something a skilled fighter could easily take advantage of. Lacy has been in several close fights in last few years, and none of them were against fighters the quality of Calzaghe. Lacy had serious problems with Sheika, Williams, Vanderpool, and Wiggens in his last 7 fights. In all of those fights he was losing rounds early and bailed himself out late by catching his opponent with a big shot. Sheika was landing the straight right at will against Lacy, but he got scared held while Lacy outworked him for the close decision.
I'm a Lacy fan, but he needs to work on straighter punches and head movement. Believe me I hope Lacy wins, I've never been a fan of Calzaghe or Warren so a Lacy win would make me happier than cashing a ticket.
A few things Lacy has going for him...he's much younger and has been much more active lately. It might take Calzaghe a few rounds to get going and you know Lacy will start fast considering the situation.
Either way I see big value in Calzaghe by decisiion +350
