Murray, at +550, is the favorite to win the Associated Press' regular-season MVP award at Caesars Sportsbook. Mahomes is next at +600, followed by Buffalo Bills quarterback Josh Allen at +800. Tampa Bay Buccaneers quarterback Tom Brady and Green Bay Packers quarterback Aaron Rodgers are each +900.
Mahomes had been the consensus favorite since the spring, when sportsbooks first began posting odds on MVP. But while Mahomes and the Chiefs are 2-2, the Cardinals are off to a 4-0 start behind Murray, who has attracted more bets to win the MVP than any other player at Caesars Sportsbook since the season began.
Murray entered the season at 25-1 to win MVP, but he quickly moved into the top tier of favorites and was 10-1 after Week 1.
Murray is completing 76.1% of his passes and has accounted for 12 touchdowns, while Mahomes has accounted for 15 touchdowns. Both quarterbacks have each thrown four interceptions this season.
Other quarterbacks are on the rise at sportsbooks, including Los Angeles Rams quarterback Matthew Stafford, who has gone from +2,000 to +1,100 at Caesars, and Dallas Cowboys quarterback Dak Prescott, who has gone from +1,200 to +1,100.
A quarterback has won the award 13 of the past 14 seasons.
