This past year, two companies, FanDuel and DraftKings, entered the national market, offering a way for sports fans to build teams on a daily or weekly basis with prize money in the millions. Entry fees are as little as $1. Their game is played basically the same way, though the sheer volume of advertising and sponsorships by these two companies has taken fantasy sports to a whole new financial level. Is it gambling? Well, sure, in the same way those NCAA tournament pools are that people fill out every March. But in most states, including Maryland, it's legal, thanks here to a 2012 bill that considers fantasy sports leagues not as betting but as a game of skill and not a form of luck. Though if you saw some of those who won in my leagues, you might dispute that luck doesn't have something to do with it.
