Overall 20/28 main cards picks correct. 

UFC 104 features a LHW bout between Lyoto " The Dragon" Machida and Mauricio "Shogun" Rua, with a co-main event featuring Cain Velasquez and newly signed Ben Rothwell. Also on the card, Anthony Johnson, looking to move up the WW ladder and Joe Stevenson who is back on track with his impressive win over Nate Diaz in LW division.

UFC 104 MAIN CARD

 Anthony Johnson vs Yoshiyuki Yoshida

Anthony Johnson is on a two fight win streak after knocking Kevin Burn's head off with a kick and beating up ex-marine Luigi Fioravanti. Yoshida is coming off a win over Brandon Wolff, and is 10-1 in his last 11. His loss to Koscheck showed off a bit of a glass chin though, which is unfortunate considering Rumble Johnson is a fan of smashing in people's faces. I'm pick Anthony Johnson by 1st Round KO of the Night.

Joe Stevenson vs Spencer Fisher

Joe Stevenson looked really good in his fight against Nate Diaz at the TUF 9 Finale, and Spencer Fisher 3-0 in his last three, spoiling Caul Uno's UFC return in his last fight, so this could really go either way. Joe Stevenson has really quick, accurate strikes, which has historically given Fisher some trouble ( Stout, Edgar ), and Stevenson definetly has the wrestling and jits to hang with him. The only way I see Fisher winning is by decision, but I think Stevenson will either take it before with a TKO or squeak out a UD. So Joe Stevenson by Unanimous Decision.

Gleison Tibau vs Josh Neer

Who cares who wins this one? I don't know how this got on the main card when people like Okami and Sonnen are fighting on the undercard. Seriously, Neer lost his last one to the gatekeeper Kurt Pellogrino, and Gleison Tibau lost his last one to Melvin Guillard. This should be on the bottom of the undercard. But because it's on the main card, I'll just pick Neer, via Split Decision.

Cain Velasquez vs Ben Rothwell

Both are top competitors in the UFC HW division, I wouldn't be surprised if the winner of this fight was next in line for a shot. Rothwell, an IFL veteran, is 14-1 in his last 15, and Cain is 6-0 overall with his last win over top kickboxer Cheick Kongo. Many people though Kongo would be next in line for a title shot before Cain stopped him.  Cain has solid wrestling and a great chin, which neutralizes most of Rothwell's threats, but Rothwell does have a decisive size advantage. I think Cain should stop Rothwell with a TKO, in the 3rd round.

Lyoto Machida vs Mauricio " Shogun" Rua

Lyoto Machida is looking to be the first LHW champ in a while to hold on to the belt for more then one fight. He's fighting Rua, who has looked questionable in his fights in the UFC. Old Man Coleman almost took him to a decision, and he was looking pretty average before he got the flash KO of Glass Chin Liddell who has been KO'd in 3 of his last 5. Machida, who gets punched an average of once every 2.5 minutes, should have no problem taking care of Rua. I'll say Machida via 2nd Round TKO.
