Some neutral facts that may or may not be relevant... just some food for thought.
-Belcher has finished his opponents in all wins since 2009.
-Only 2 of Belcher's 18 wins have gone to decision.
-The last time Belcher was finished was in 2008, by Jason Day (TKO). He has lost two decisions since then.
-Half of Bisping's wins since 2007 were by TKO, half have been by decision.
-Half of Bisping's losses since 2009 have went the distance, half were TKO/KO.
Bisping's past 5 losses (3 Dec, 1 KO, 1 TKO): Vitor Belfort, Chael Sonnen, Wanderlei Silva, Dan Henderson, Rashad Evans
Belcher's past 5 losses (3 Dec, 1 TKO, 1 Sub): Yushin Okami, Yoshihiro Akiyama, Jason Day, Kendall Grove, Yushin Okami
Bisping's past 5 wins (3 Dec, 2 TKO): Brian Stann, Jason Miller, Jorge Rivera, Yoshihiro Akiyama, Dan Miller
Belcher's past 5 wins (2 TKO, 3 Sub): Rousimar Palhares, Jason MacDonald, Patrick Cote, Wilson Gouveia, Denis Kang
Of course there are many other factors to consider if making a prediction, but these are some interesting facts
I personally have Belcher ranked higher than most other people do, and I believe it is deserved. I have actually gained respect for Bisping over the past few years, but I think Belcher takes this one.
