Yep, I'd agree with you there. I think all in all, Calzaghe did well to win by that margin. Forget style, Sakio Bika had none, and was determined to out-headbutt, out-wrestle and out-muscle Calzaghe.
I think Calzaghe lost in the strength department, but his technical skill and actual boxing were sublime. He lost his head a few times by ignoring the southpaw stance of his, and being drawn into a battle, which he did well at the start, but failed towards the end. Dropping his arms was a silly reckless thing to do, but he cared to much about that non-existent American respect.
I want him to fight Kessler and then retire, hopefully as a great.
