But if the National Football League had its way, prop bets would be prohibited as too vulnerable to match-fixing.
In September, NFL Executive Vice President Jocelyn Moore asked Congress to let leagues and regulators ban bets that involve the performance of individual athletes.
But Joe Asher, CEO of bookmaker William Hill US, says he’s never seen a player proposition bet being manipulated to fix the outcome.
These bets account for a small percentage of regular-season sports bets, but will be more popular during the Super Bowl.
