LAS VEGAS -- Casinos in Las Vegas think Aaron Rodgers and the Green Bay Packers have a better shot at winning the Super Bowl than Tim Tebow and the Denver Broncos have of getting past the Pittsburgh Steelers this weekend.

Oddsmakers at Cantor Gaming have the Packers as 9-5 favorites to win the Super Bowl on Feb. 5, and the Broncos as 120-1 underdogs to win the NFL title.

But the Packers (15-1) are weak enough on defense to make it more likely that another team will prevent them from repeating as champions, Cantor Race & Sports Director Mike Colbert said.

"Offense seems to rule the day right now in the NFL, but I'm not sure that defense will be able to hold up long enough to win it all," Colbert said.

Sports gambling expert RJ Bell of Pregame.com says that after adjusting for fees, sports books think the Packers, the top seed in the NFC, have a 32 percent chance of winning the Super Bowl.
