Make Trades on Tuesday Night NBA Games
| Matchup | Probability |
|---|---|
| Philadelphia 76ers @ Boston Celtics | 18.75% / 81.25% |
| Atlanta Hawks @ New York Knicks | 30.56% / 69.44% |
| Portland Trail Blazers @ San Antonio Spurs | 16.33% / 83.67% |
Putting your $20 bonus to work on today’s slate offers vastly different payouts depending on your strategy. If you back the heaviest favorite on the board—the San Antonio Spurs at an 83.67% probability—a winning prediction nets you a modest $2.96 in profit. On the flip side, taking a swing on the heaviest underdog, the Portland Trail Blazers (16.33%), yields a massive $97.60 in profit if they can pull off the upset.
When deciding where to place your predictions, standard handicapping points heavily toward the home teams looking to close out their series tonight. Based on the previous playoff games in each series, Boston is a dominant force. The Celtics boast a stellar 14.0 Net Rate and are dominating the glass with 55.9% of all available rebounds. Meanwhile, the 76ers are struggling to find answers, posting a -14.0 Net Rate and securing just 44.1% of rebounds.
San Antonio commands a similar statistical edge. The Spurs carry a strong 10.8 Net Rate and a 52.2% total rebound percentage over the course of the series, while the Trail Blazers lag behind at a -10.8 Net Rate and a 47.8% rebound percentage, making Portland a highly risky wager despite the lucrative payout potential.
