I keep pushing for a legalization of betting in Sports, as I believe that as long as stuff like smoking isn't banned, gambling should be ok. And with some smart combination of legal age, pre-paid activities and maximum stakes across industry you should be able to track and influence the behaviour of 98% of sports fans, the 2% being those who will ruin their lives over gambling anyway, be it legal or not. As soon as you start betting on a game, it becomes more and more exciting. The most lame and boring, 3-0 standing soccer match from Sweden becomes fun when you can bet on which team will score next, who will have the next corner and so on. How great for any TV station showing sports! And when betting meets fantasy, the whole thing becomes even more exciting. If you don't believe me, look at the numbers from FanDuel and DraftKings. Any professional Sports league (or even clubs) should be very interested in their business models.
