Think wagering $20 to win $1 million by picking a winning combination of NFL players for a fantasy team is gambling? As the NFL season ramped up this weekend, the league says it’s not. So do fast-growing daily fantasy sports companies like DraftKings and FanDuel that offer the games and advertise with teams in the long gambling-adverse pro football organization. But that has Las Vegas casinos and sports books feeling like they’re on the wrong end of a double-standard that bars traditional sports betting outside a handful of states, including Nevada, but allows daily fantasy sports in most of the United States. The chief of sports book William Hill’s U.S. operations, Joe Asher, says no one should pretend that one is OK and one isn’t. He and others in the casino industry argue that both should be legalized and regulated.
