2 great boxers will fight for the WBO belt in 2015. Saunders is undefeated in 21 fights but he's not a KO artist, shown some vulnerabilities against Eubank Jr who he beat by Split Decesion last month and became the challenger to the WBO belt. Andy Lee(34-2-0) is the current champion, he KO'd a top opponent(Korobov) this month and won the belt. He's in top shape. I'd say Lee wins by points or late KO.
Billy Joe is more skilled than given credit for. Lee isn't that skilled and shouldn't land too much. Saunders and Eubank have been mutually beneficial as they have both had a tough learning fight and both come out with credit and the judges were split over who won. Saunders wins the WBO in March and defends it probably against a British name in the summer, maybe Murray if he loses with credit to Golovkin. Eubank beats Chudinov in February and wins the WBA off Jacobs in the summer and then maybe they rematch to unify in November/December in a huge grudge match.
