I get the feeling he'll go for the guy who has 12L on his record - Glengoffe.
Dawson would, and should, be the best fight for him but I don't think he'll take the risk. Maybe Calzaghe-Veit III?! http://images.digitalspy.co.uk/forum/smilies/yawn.gif
one can't help but to say those things about Dawson for his two fights in 2008. Beating an former champion in Tarver and a close fight with Glen Johnson.
As far as Dawson's popularity in America, he is still an unknown expect to hardcore boxing fans. I think you read too much in here (NSB) to assume that.
IMO, I say Calzaghe is sitting out for his "Mayweather/ Hatton" type fight, a huge draw and a HOF career. Who that is, I have no idea.
