BetMGM Sportsbook has the Celtics as a big 11.5-point favorite on Friday night. This offer can be used on any NBA, NHL, NCAAB, or sporting event on BetMGM. We'll zero in on the Nets-Celtics to explain how you can use the BetMGM bonus code.

Betting Nets-Celtics with BetMGM's Bonus Code

The Boston Celtics have been the league's best team throughout the season. The Brooklyn Nets were in a position to give them a run, but the trades of Kyrie Irving and Kevin Durant moved them down the standings.

We know BetMGM is heavily favoring the Celtics in this matchup. Our Andrew O'Connor-Watts is taking a different approach to betting on the Nets-Celtics.

I can only look to the Celtics or the over in this matchup. Boston is favored by 11.5 points. That’s too rich for my blood. And the Nets offense has been horrible, so I don’t trust them to help with the over.

So, I’ll look to play a combination of the two by betting on the Boston offense and fading the Brooklyn defense.

In the past three games, opponents are averaging 129.7 points per game against the Nets — the third-worst mark in the league, according to Team Rankings.

Meanwhile, the Celtics are second in the league to their team total over this season (21-11). In their past 10 games, Boston’s team total is 7-3 to the over.

Take the Celtics team total over to 120.5 or better.

BetMGM Sportsbook gives the Celtics +110 odds to clear 120.5 points. Here is how it'd play out if you bet $100 on that prop.

• If the Celtics score over 120.5 points, you'll win $110 and keep your $100 wager.
• If the Celtics don't hit 120.5 points, you'll receive $100 in bet credits.

How to Use BetMGM Bet Credits

Bet credits aren't available for withdrawal, so you must win a bet to withdraw your money. You also only keep your winnings when betting with bet credits.

BetMGM is offering a promo for the Nuggets to lead at the end of every quarter in their matchup against the Grizzlies on Friday night. Let's see what happens if you bet $100 in bet credits on the promo at +210.

• If the prop hits, you'll win $210 but not your $100 wager.
• If the prop fails, you lose all your bet credits.
