The league continues to fight legal efforts that would effectively let states other than Nevada and Delaware introduce sports gambling even as leagues like the N.B.A. and the N.H.L., which have stood with the N.F.L. in court, have softened their stance on the issue. The N.F.L. also continues to penalize players and other league personnel who are paid to appear at casinos even as team owners collect millions of dollars from sponsorships with casinos, state lotteries and fantasy football providers, and play games in England, where sports betting is legal.

Just this month, for example, several players participated in an arm wrestling event at the MGM Hotel and Casino on the Vegas Strip, and the league is considering whether to fine them for those appearances.

“How can you have a franchise there and not allow players to participate in arm wrestling contests?” said Scott Rosner, who teaches sports law and business at the University of Pennsylvania. “When you get into the weeds, the policies may not be as inconsistent as they seem, but the optics are that the league is very inconsistent on this.”

The N.F.L., though, will remedy these contradictions, Rosner said. The Raiders will play in Oakland for at least two more seasons, giving the owners time to revisit their rules and bring them more in line with the reality that gambling has become far more ubiquitous than the days when gamblers had to place bets through a bookie or at a racetrack.

The N.F.L. is often criticized for having a double standard on gambling, in part because the public seems to be more accepting of betting on games. A recent poll by researchers at Seton Hall University found that just 21 percent of respondents thought the N.F.L. was tarnishing its reputation by putting a team in Las Vegas. While it’s hard to imagine another American city prompting such a negative reaction, it is also a far smaller percentage than might have been the case even a decade ago.
