Knicks-Mavericks Same Game Parlay Options

With your BetMGM welcome bonus and promo code, you can make a brilliant range of same game parlay picks for the upcoming Knicks/Mavs game. We have the Knicks as the favorite for this game as Dallas have not looked great without Anthony Davies or Kyrie Irving, despite the efforts of rookie Cooper Flagg. Still, despite the expected outcome, there’s plenty of room for some interesting SGP picks at BetMGM, such as the following:

Copper Flagg: Over/under on points, assists, or rebounds.
Karl Anthony Towns: Over/under on points or rebounds.
Mikal Bridges: Over/under on points or steals.
Jordan Clarkson: Over/under on points.
Max Christie: Over/under on 3pters made.
Klay Thomspon: Over/under on 3pters made.
Derrick Lively: Over/under on rebounds.
