The National Football League returned for another season last night. With its full game slate launching Sunday, the NFL’s business partners, including the gambling mavens over at DraftKings Inc., are excited.

“FOOTBALL IS BACK,” DraftKings tweeted, touting its new partnership with the NFL and a $1 million sweepstakes that customers who download its mobile app can enter for free. DraftKings, a leading operator of fantasy sports leagues and digital betting platforms based in Boston, has been on a roll. It recently said it plans to buy Golden Nugget Online Gaming Inc., a cyber-casino and sports-betting operation, for $1.6 billion.
