Former UFC middleweight champion Anderson Silva already is a 2-to-1 favorite over the man who just took his title, Chris Weidman , should a potential rematch happen. Veteran oddsmaker Joey Oddessa on Tuesday confirmed the opening lines with MMAjunkie.com (www.mmajunkie.com). Oddessa said the line opened at -175, but within the first few hours already had been bet up to -200 for Silva. Silva (33-5 MMA, 16-1 UFC) put his title on the line against Weidman (10-0 MMA, 6-0 UFC) at this past Saturday’s UFC 162. After a first round that saw Silva win on one judge’s scorecard, but Weidman on the other two, Silva started the second by continuing a pattern he has shown in the past – trying to bait his opponent in by ducking and dodging and asking Weidman to hit him. But right after getting hit and playing possum, Silva got hit with a Weidman left that put him on the canvas, and a few quick shots on the ground later his 16-fight UFC win streak and 10 middleweight title defenses had gone by the wayside. UFC President Dana White said following the event that he’ll be pushing for a rematch – even though Silva said Weidman is the new champion and he doesn’t want to fight for the title anymore.
