Keep an eye out for offerings from sportsbooks for new customers as bet365 debuts in two new states and other books look to compete for new action during March Madness.  

Best Cooper Flagg bets for March Madness 

Flagg finished the regular season with averages of 18.9 points, 7.5 rebounds, 4.1 assists, 1.5 steals, and 1.3 blocks per game while shooting 48.8% from the floor. His minutes could be limited when Duke faces No. 16 seed Mount St. Mary's on Friday. 

Loaded with experience and talent beyond Flagg, the Blue Devils are the No. 1 seed in the East Region, with Alabama, Wisconsin, and Arizona checking in as the other top seeds in the region. Duke is getting short odds of around -300 to reach the Elite Eight and is closer to even money — around -120 — to make the Final Four. 

At FanDuel, Flagg is the favorite to win Final Four Most Outstanding Player at +370 odds. He is the favorite (-220) to win the Wooden Award as the best regular season player.

In the head-to-head market, or Team to Advance Further, you can get Duke at -125 odds to get farther than Auburn (+105) at DraftKings. The book offers +150 odds for either Duke or Auburn (the No. 1 overall seed) to win the tournament and +320 odds for Duke vs. the field. 

Odds boost tokens are being offered at BetMGM along with a free contest called March Matchups, where customers can pick games and answer questions to earn a share of a $250,000 prize pool of bonus bets. 

Individual markets and bets are often boosted at bet365, along with specific parlays. Keep an eye out for changes to odds in Duke games as the tournament progresses. The book also offers an early payout promotion where moneyline bets cash if the backed team is leading by 15-plus points. 

Markets are also available at most books for which NBA team will draft Cooper Flagg. He is expected to be the No. 1 overall pick if he declares for the draft, but the star forward has left the door open for a return to Duke. 

Best Bet for Cooper Flagg in March Madness 

Final Four Most Outstanding Player (+370 at FanDuel) 

Flagg has lived up to the hype at every juncture throughout his early career, and shining on the biggest stage would come as no real surprise. The Blue Devils’ supporting cast should help him reach the Final Four, with Duke earning a relatively favorable draw in the East Region.

Flagg’s game is less dependent on outside shooting since he can score at all three levels and make a significant impact with his defense. If he wins a head-to-head matchup against another star in the national championship, it will be hard for voters to pick another candidate for this award.
