Carolina had hit as high as a six-point favorite in the big game at sportsbooks monitored by Odds Shark as of late Monday. Some books opened the Panthers as 3.5-point chalk, but that number quickly disappeared after they steamrolled the Arizona Cardinals 49-15 in the NFC Championship Game.
Even though the best time to wager on Carolina has likely passed, Denver backers are still patiently waiting for the perfect opportunity to bet on the underdog.
Whether the Super Bowl 50 line hits the magic number of seven points remains to be seen, with much of the betting action in Las Vegas taking place late in the week.
Getting six points with the Broncos might be as good as it gets, and many books still have them at that number.
This is also true with the moneyline, which involves simply wagering on the team you think will win Super Bowl 50. The best plus-200 price (bet $100 to win $200) you can get on Denver right now will probably not last much longer either unless money on the Panthers pours in to push the point spread to seven.
However, bettors who like the under to cash in what they think will be a defensive battle might want to wait as long as possible. The total opened as low as 44 points and is now as high as 46 points, and the public generally wagers on the over.
The Broncos bring the league's top-ranked defense into Super Bowl 50, and their best chance to win may be in a low-scoring game. Carolina's lone setback of the season was a 20-13 road loss to the Atlanta Falcons in Week 16. In the past five games for the Panthers, that is the only under that has cashed in.
Taking Denver and the under together will be a popular corresponding parlay for many, as will Carolina and the over. But Peyton Manning's ability to keep the Broncos competitive in a high-scoring affair and possibly pull off the upset in what could be his final game before he retires would spoil both possibilities.
