Just because someone hasn’t asked for something in the past, it doesn’t preclude someone from asking in the future. States are in a position to profit greatly because of the popularity of the sports leagues. I think it’s fair for the leagues to ask for a cut.
Of course the leagues’ stances on gambling has been inconsistent and hypocritical. That point is obvious.
With sports betting only being legal in Nevada, I think it made some sense for the leagues to maintain some distance. Now that it’s likely to be legal in many states, it makes more sense for the leagues to ask for a share.
