Things change in a hurry for Vegas when it comes to betting and money. Just a few days ago, the Arizona Cardinals had the shortest odds for winning the Super Bowl. Now, after they squeaked into the NFC title game with an overtime win over the Green Bay Packers, combined with other teams winning and losing, they have the longest odds.
In the most recent odds from Bovada, the Cardinals' odds to win it all went down slightly from 17/4 to 4/1. However, the Carolina Panthers and New England Patriots are now the odds-on favorites.
