NBA Finals: Celtics favored but money is rolling in on Mavericks

LAS VEGAS — The Celtics are prohibitive favorites to win Thursday’s Game 1 of the NBA Finals and odds are on Boston to hoist what would be its record 18th championship banner. But the money, at least at Bet MGM Sportsbook, is pouring in on the Dallas Mavericks. Senior trader Halvor Egeland said Monday that 80% of the bets were coming on Luka Doncic, Kyrie Irving and the Mavs to win their second NBA title. Boston is a -225 favorite to win it all, meaning someone would need to wager $225 to win $100.
