Wlad was at his most exciting against Pulev. I was quite surprised at how entertaining that match turned out to be.
Erislandy Lara had a really exciting performance against Hurd, arguably FOTY. His fight against Angulo was also pretty entertaining as well.
Wright vs Vargas was much better than some could of expected with Wright adopting a more aggressive style than he used before.
Bradley against Provodnikov, maybe? I think the backlash from his dubious verdict over Pacquiao, and the poor reception of his unification against Alexander, really lit a fire under Bradley for that one, and he was determined to put his stinker reputation to bed. Guess you could argue that Provodnikov was never going to allow a turgid fight, but Bradley definitely forgot his scrappy, low-key style for that one.
Ivan Calderon's fight against Giovanni Segura was really exciting. It was considered FOTY of 2010. Derrick Gainer's KO loss to Kevin Kelley was also a great fight.
The obvious, Floyd early in his career was much more entertaining then when he moved to 140. Rigo certainly has had a couple good bouts where he looked beastly for a change. I guess one might say Ruiz versus Jones. One of the few fights Ruiz was somewhat entertaining, as opposed to his usual hugfests. Bernard had plenty of snoozers too. But his fights w/ Tarver, Tito, Calzaghe, Pascal... pretty decent bouts.
