IMO on Saturday Roy has more to worry about than Calzaghe, people forget that Joe has respectable power when he actually throws punches properly. Therei s a reason he has 32 ko's, why Lacy and kessler felt his power. I think when Calzaghe throws combinations he tends to get slappy, but it effects his opponents as Kessler can atest to. I think I could see Roy getting ko'ed easier then I see Joe getting ko'ed simply because Roy couldn't stop Trinidad, not because he couldn't I guess, but because he doesn't back up his work anymore, he throws a few punches, but he can't step on the peddle after that, and against Joe that is big trouble because Kessler was able to outbox Calzaghe punch for punch earlier on, but everytime he did that Calzaghe would step up the pace and drown Kessler's effectiveness with his workrate.
