Bute is a good puncher, but he doesn't have the heart to come with it, which is why he lost to Froch.
I don't want to sound anti-GGG here, I think he's the real deal and I'd make him the favorite over every MW, only Lemieux may have the power to hurt him, but SMW is a whole different kettle of fish and Froch has not shown any signs of rust or degradation in my opinion, I think he thought he could just go in there and blitz Groves out of the ring in their first match, and he didn't know Groves hit as hard as he did (if the reports are true he dropped GGG in sparring as well) but Carl boxed beautifully in the rematch set traps for GG and KHTFO, Carl WILL fight cautiously against GGG, he won't make that same mistake again, and GGG WILL fight cautiously aganst Froch, he'll fear the power of Froch as well.
Golovkin is the best middleweight in the world today. Cotto will give up his title rather than fight him..................Golovkin said he would fight Void at 154, but Void ran like Hell, even with his personal referee, judges, boxing commission, etc................
