i am not 100% sure about his management structures but most of his fights 'i can remember' are presented by goldenboy promotions.
if he is against a golden boy fighter, of course it will be presented by golden boy (co-presented is more correct). but he is with the Top Rank :deal
Vitali isn't in or around the same weight as Pacquaio, Hatton is. Pac is the P4P #1 and therefore is the betting favourite. Duh. What has Vit Klit got to do with this rather obvious fact?
Because Oscar was a natural junior middleweight who had fought Bernard Hopkins, whereas Pac had fought as low as Flyweight. Hatton and Pac are similar weights and sizes, but Pac is the P4P King so he is obviously the betting favourite.
