I think it's between Calzaghe, Pacquiao, and Margarito. Hopkins has a loss on his record this year (even though it's controversial, a loss is a loss).

Calzaghe needs to beat Jones and then he would be a good candidate to win it. Even though Jones and Hopkins are past it, on paper it looks pretty sweet.

Pacquiao won the Ring Magazine title from Marquez at 130 then took a title from Diaz at 135. If he wins against De La Hoya, then he's a no brainer for fighter of the year.

But, unless Calzaghe beats Jones and Manny beats Oscar, Margarito is ahead in the fighter of the year race.
