Calzaghe is a dam good boxer, but as Britkid said on a old post, Calzaghe has 3 fights left in him maximum (putting aside that BK wants him to retire now).

I can see :
1) the bum bika KO7
2) Wright UD
3) Taylor

Taylor will have no other option than fighting the man who defeated Winky....it would be an awesome retirment plan ^^
