I think the question of could is always a maybe. None of us can say this guy can't get knocked out or this guy can't do it. But in this case it wasn't likely as stated because Winky is too slick and defensive to be caught like that much. But I do believe Taylor's punches were definitely starting to hurt.
I don't think Calzaghe would do well going up in weight, actually think Lacy might be better served to move to light heavyweight than Calzaghe. Do think Joe could do very well with his speed and power at Middlewight. Then he would have more options for a name fight.
Most people don't care for Larry Merchant because of his attitude and tone. I didn't like him at first because I thought he was an ass and disrespectful to the fighters. But the more I see him ( or listen) the more I am getting used to his ways. I have even come to appreciate his approach since I think he is one of the only boxing commetators to cut through the fighters' hype and bs and make them be honest. If they got hteir butt whupped he says it. If they won against a very overmatched fighter, then he will try to humble them a bit. And hey, look at it this way, he makes us laugh with some of the ridiculous things he says.
