Sports Leagues Will Plead With the Federal Government for "Integrity Fees" from Gambling Anyways, the other thing you’ll notice is that all three of them used the word “integrity” in their statements. This is a reference to the “integrity fee” that they are trying wedge into state bills. Their argument presumes that the amount of betting will rise substantially enough that they’ll have to up their scrutiny to make sure games aren’t fixed. As Mike Florio pointed out in a story about West Virginia’s bill, Nevada has had legal sports betting for some time and they do not pay an integrity fee to the leagues. The NFL spent millions of dollars trying to figure out if Tom Brady deflated footballs, and wound up with results that were inconclusive at best. The leagues already have every incentive to make sure their sports are on the level.
