How to Use Your Underdog NBA Promo Tonight

Tonight’s Eastern Conference clash sees the Boston Celtics travel to face the Miami Heat. Both teams enter the contest with significant players sidelined. The Boston Celtics will be without star forward Jayson Tatum (Achilles) and Josh Minott (Ankle).

The Miami Heat are also shorthanded, missing key guards Jaime Jaquez Jr. (Knee) and Davion Mitchell (Shoulder), which will force others to step into larger roles. Statistically, the Boston Celtics have been one of the league’s top teams, boasting a net rating of +6.5, while the Miami Heat have a solid +1.7 rating.

Boston Celtics vs Miami Heat Statistics & Analysis

With key players out for both squads, others will have ample opportunity to exceed their statistical averages. Jaylen Brown, in particular, sees his usage rate soar to 36.63% without Jayson Tatum on the floor. His points line is set at 29.5, right at his season average, making the higher number an intriguing look given his expanded role.

For the Miami Heat, Norman Powell could be a primary beneficiary of the backcourt injuries. He is averaging 23.8 points per game (811 points in 34 games), and his line is set at 21.5. Another Miami Heat player to watch is Andrew Wiggins, whose 3-point line is 1.5. He is averaging 1.86 made threes per contest on a strong 39.88% shooting, making the higher number a solid proposition.
