Main card 
Heavyweight bout:  Brendan Schaub vs.  Gabriel Gonzaga    
Well based on previous fights neither one of these guys can really take a good hard punch.  Gonzaga is pretty good on the ground so if it goes there he should be fine.  Schaub is just here because he made it to the finals of TUF.   
Gonzaga wins this one     
Light Heavyweight bout:  Tito Ortiz vs.  Matt Hamill    
I hope to see Matt Hammell's def ass beats tito into a different timezone.  Tito is a shell of the fighter he used to be and whoever put him in this fight must really want to see him look bad.   
Hamill wins this one and leaves with Tito's old lady.     
Welterweight bout:  Diego Sanchez vs.  Paulo Thiago    
Now this could be a good fight.  Sanchez fights like he has a hot poker stuck in his cock hole and Thaigo is a certified bad ass.  Sanchez is really good on his feet but I think Thiago's ground game is what gets him by.   
Thiago wins   
Welterweight bout:  Jake Shields vs.  Martin Kampmann    
I really don't know about this fight.  Shieds fights are about as entertaining as doing your taxes drunk.  Kampmann, when he is on will KO someone.  Winner of this gets to be fed to GSP next.  I dont even know if I will watch this fight, might be the food and bathroom break.   
I am going with Kampmann just because he looks scary.   
Heavyweight Championship bout:  Brock Lesnar  vs  Cain Velasquez    
This one is simple, Cain is able to expose Brock's lack of boxing he wins.  Cain does not do this please see results of Brock's other fights.  Druing "brocktober" on spike they have shown enough of his fights, and it is scary to see his progression as a fighter.     
Brock wins this
