They are making money from it.
When sports gambling suits a sports owner, or makes a sports owner money, then there is no problem with sports gambling. That was true when sports leagues started teaming up with fantasy sports which really was sports gambling not a game of skill, and that trend has continued since the Supreme Court of the United States legalized sports gambling and allowed sports gambling to expand beyond Nevada and Delaware. When customers approach the New Jersey Meadowlands for a Jets or Giants home game, there is a sports book in the East Rutherford, New Jersey complex and the Jets franchise has a business deal with MGM Resorts that brings money into the business. The irony of that is simple. New Jersey was the epicenter of the battle between sports leagues, particularly the National Football League, and states over legalized sports gambling. New Jersey wanted the betting, the NFL sued and kept winning in lower courts. But the Supreme Court in May overruled the lower courts and suddenly New Jersey had sports betting. The NFL was not the only sports league to say no to sports betting in New Jersey. In the 1990s, National Basketball Association Commissioner David Stern lobbied against sports gambling in the Garden State.
In August, 2018, National Basketball Association Commissioner Adam Silver signed a deal with the Las Vegas-based MGM Grand Hotel, which is also a sports betting casino that allows the hotel to become the Official Data Partner of the NBA. The deal brings $25 million into the league and allows the hotel and other properties that MGM owns in Las Vegas to use NBA logos and more importantly NBA data in the hotel’s sports books. The NBA boss thought that sports betting will increase interest in his product, basketball games. The National Hockey League also has a deal with MGM. The leagues like the gambling money.
