Machida-Ortiz: I think it will be close, but unless Tito wins decisively, there's no way he's going to get a tight decision. Machida grinds out a close and somewhat boring decision... but I wouldn't be surprised if Ortiz ground and pounded a TKO. Machida split decision. Crowd cheers Tito, even though he doesn't get to speak on the mic. (I'd love to see him KO Dana White.)
Silva-Jardine: Wanderlai is on the downside of his career and is somewhat undersized at 205, but I think he pulls this one out. More of a gut instinct/heart pick than anything else. Jardine is a solid, but not spectacular all-around light heavy and is a brutal striker (best leg/body kicks at 205+ with CroCop pretty much done perhaps?) so this should be a great fight to watch for the casual fan. Wandy by KO.
Penn-Sherk: I see this unfolding much like the first Penn-Matt Hughes fight. Penn outstriking on the feet and then befuddling the wrestler on the ground, leading to a submission - probably a rear naked choke. Sherk is a strong wrestler at 155, but I just look at his results against good, but not great BJJ fighters in his last three fights and think that BJ Penn will find the opening and exploit it. Penn by rear naked choke in round two. (I'm tempted to say round one.)
When it's all said and done, BJ Penn may go down in history as the greatest MMA fighter of all time.
Other fights:
Thiago Silva-Antonio Mendes: I think Zuffa is protecting Silva in this one by putting him in with a guy that hasn't fought any big names. But in the last two years, we've seen an obscene amount of "upsets" and Silva hasn't really fought that many top fighters either. I'm picking Thiago, but this fight just screams upset because of Medes' experience (16 fights).
Wilson Gouveia-Goran Reljic: I know Zuffa is pinning its hopes on Reljic, but Gouveia has much more experience against a higher level of opposition. I'm picking the Croatian by KO, but I don't believe the hype 100%.
Rameau Sokoudjou-Kazuhiro Nakamura: I hope Sokoudjou can rebound from his last fight against Machida, otherwise his wins over Arona and Lil' Nog (a favourite of mine) were for nothing. Nakamura's a tough fighter with a good beard, so I'm a little worried about Sokou, but I'm still going to pick him by TKO.
Ivan Salaverry-Rousimar Palhares: I think Salaverry could be in trouble. Rousimar is one of the top fighter/trainers from the Brazilian Top Team. Ivan will have to use his height and reach advantage as much as possible... Rousimar by submission.
Interesting note - look at how far down the fight card UFC puts the Tito-Machida fight:
