BetMGM Massachusetts Promo Code for the NBA or Final Four

The Celtics have the second-best odds to win the NBA Finals, just behind the Bucks. While these teams have secured a playoff spot, there are several other teams that are still fighting for a position in the postseason. This includes the Mavericks, who are currently in 11th place in the West. They are four-point underdogs on Wednesday night against the 76ers.

Bettors can also use the BetMGM app for the Final Four. On Saturday night, it will be Florida Atlantic vs. San Diego State and Miami vs. UConn. The Huskies are favored to win the National Championship.
