Seizing on the legalization of sports gambling in Colorado, the Broncos completed their blitz of the market Thursday by signing a multi-year partnership with BetMGM. Last month, the Broncos announced deals with FanDuel and Betfred USA. The highlight of the Broncos-BetMGM deal is the NFL’s first in-stadium sports betting lounge. “As we think about the sports market in Colorado, the first team we think of is the Broncos,” BetMGM chief marketing officer Matt Prevost said in a phone interview.
