I don't understand why people are thinking that this is a bad card. Sure, Wanderlei pulling out hurt some of its "star power" a bit, but I'm still excited as all hell about the other f!ghts.
Leben is still in f!ght shape, and honestly, there's not much difference between his and Wanderlei's brawling style. Wanderlei probably has better BJJ, but other than that, stylistically, I don't think that Akiyama has to change up his gameplan all that much.
Chris Lytle has a k!ller chin, and has four "f!ght of the Night(s)" on his resume. He always puts on entertaining f!ghts.
Bonnar/Soszynski is the f!ght I'm probably LEAST excited about on the main card, but I think that it'll still be a decent one.
Sotiropoulos/Pellegrino is actually my pick for "f!ght of the Night." Both dudes have GREAT BJJ, with Sotiropoulos probably having some of the best BJJ in the LW division outside of BJ Penn. Neither guy "stalls" on the ground, and both are always active. Will someone get KO'ed? Probably not, but it'll be exciting for sure.
