LAS VEGAS -- Some thoughts about what to look for at UFC 168 on Saturday night (besides just the punching and the kicking and the grappling):
-- How does Uriah Hall respond after two losses and that "He's not a fighter" quote by UFC president Dana White from the last time he fought? That should be quite interesting to watch unfold against Chris Leben.
-- Can Miesha Tate push Ronda Rousey to a second round for the first time in her career? That would be a win of sorts for Tate, who isn't being given much of a chance at winning this fight. White said it would be the second greatest upset in history if she did Rousey. The oddsmakers agree. Tate is going off at anywhere from +650 to +1000 to win. Long odds, but great value if it hits.
-- Could this be the start of something for Gleison Tibau if he beats Michael Johnson? The Brazilian lightweight is on a two-fight win streak and has only won three in a row twice before in the UFC (13-7). He's a tough fighter with a solid BJJ game, but Tibau never seems to put it all together for a sustained run.
-- Diego Brandao missed weight by seven pounds on Friday, costing him 25 percent of his fight purse. He and Dustin Poirier had an exchange of sorts at their staredown as well, which is rather amusing seeing how Brandao missed the featherweight maximum of 146 pounds by about two cans of soda and a three-foot meatball hero.
-- After putting together a seven-fight win streak, Miller is 2-3 since August 2011. Have to think that a loss here to Fabricio Camoes won't bode well for another run at a title shot.
-- Of course, there's the main event as well and the intrigue surrounding Anderson Silva (as usual). Will he be a showman again (like he has been in just about every fight the past several years)? Will he play it straight and come out firing? Can Chris Weidman remain as mentally tough as he has been the past six months and dip his foot in the same river twice? We'll find out in a few hours.
