Using Your Lineups for Game 4 in Cleveland
With your $55 in Boom lineups ready to fire, tonight’s game gives us a prime slate of NBA player props to handicap. Both the Knicks and Cavaliers are loaded with star talent, giving us plenty of intriguing angles for our entries.
Below is a breakdown of the consensus over/under lines for the five players with the highest expected point totals in tonight’s matchup:
| Player | Points O/U | Assists O/U | Rebounds O/U |
|---|---|---|---|
| Donovan Mitchell | 26.5 | 4.5 | 4.5 |
| Jalen Brunson | 25.5 | 6.5 | 3.5 |
| James Harden | 18.5 | 5.5 | 4.5 |
| Karl-Anthony Towns | 16.5 | 4.5 | 11.5 |
| Evan Mobley | 15.5 | 3.5 | 8.5 |
When I’m handicapping these lines against current postseason averages, a few sharp trends immediately jump out at me.
New York’s Jalen Brunson enters tonight’s game with a points prop set at 25.5. Over the course of the postseason, Brunson has been the absolute engine of the Knicks’ offense, averaging an impressive 27.8 points per game. Because his scoring average clears the current total by more than a full bucket, the data heavily suggests locking in the over for Brunson’s point total.
On the Cleveland side, Donovan Mitchell boasts the highest points prop of the night at 26.5. However, Mitchell is currently averaging 25.7 points per game. Since his postseason scoring output sits slightly below the Boom projection, playing the under on Mitchell’s points could be a savvy, data-backed key for our lineup.
Meanwhile, Cavaliers guard James Harden sits with an 18.5-point prop. Harden is averaging 19.6 points per game so far in the playoffs, indicating that backing the over on his scoring total could yield excellent value. Tying these specific legs together is exactly how we use our bonus funds to confidently build a winning entry!
