One week after the start of free agency, Bovada.lv released their new Super Bowl odds.
The Buffalo Bills currently sit at 50/1. Buffalo shares these odds with the Atlanta Falcons, Chicago Bears, Detroit Lions, Los Angeles Rams, New Orleans Saints, New York Jets, Philadelphia Eagles, Tampa Bay Buccaneers, and Washington Redskins. Back on February 8, Buffalo sat at 33/1 odds. They've dropped down a bit, perhaps due to some of the players released or lost in free agency.
It should be noted that these odds were released before the Bills signed Jim Dray. All joking aside, the Bills haven't been and won't be very active in free agency so their odds will likely remain the same until the NFL draft. If the team has a strong draft in the eyes of Bovada.lv, their odds could improve.
Currently, the Patriots have the best Super Bowl odds at 15/2. These odds may actually improve following the team's trade for Martellus Bennett.
