This one has all the makings of a classic. And the fact they dislike each other should only add to the pace. Two strong ground guys with heavy fists and reinforced chins. As with any B.J. Penn fight, advantage goes to his opponent if it goes into the late rounds, but by that time, B.J. should have done enough damage to take a decision. My prediction is that it won't get there.
B.J. PENN IN A THIRD-ROUND SUBMISSION
Lyoto Machida vs. Tito Ortiz
Machida is one of the most underestimated fighters in the world. The undefeated 12-0 scrapper should dominate Ortiz every round, but the slippery Huntington Beach Bad Boy won't be submitted. An Ortiz loss would be too bad because the highlight of UFC 84 could be Ortiz's microphone time if he wins.
MACHIDA BY UNANIMOUS DECISION
Keith Jardine vs. Wanderlei Silva
Silva is coming off three straight losses to a Who's Who of mixed martial arts (Chuck Liddell, CroCop and Dan Henderson), but he's due. Jardine is coming off a win over Liddell but he's never fought anyone with the raw aggression Silva brings to the cage.
SILVA IN A SECOND-ROUND TKO
Thiago Silva vs. Antonio Mendes
Mendes has an impressive 14-2 record, but he hasn't fought anyone with the multi-faceted attack of Silva. The undefeated Silva will make short work of his fellow Brazilian.
SILVA IN A FIRST-ROUND TKO
Wilson Gouveia vs. Goran Reljic
This will be Wilson Gouveia's sixth fight in the big show, but the upstart Reljic seems by all accounts to be the real deal. Unlike his countryman CroCop, I think this is one Croatian who will find a home in the UFC.
I'll go with the upset and pick Reljic with a third-round submission.
