| Player | Team | Pick |
| Victor Wembanyama | San Antonio Spurs | Higher Than 0.0 Points + Rebounds + Assists |
| Paul Reed | Detroit Pistons | Lower Than 8.5 Rebounds |
| Jaylen Brown | Boston Celtics | Higher Than 6.5 Rebounds |
Lock in Victor Wembanyama as your Gimme Pick for a 1-day NBA-only entry. You can adjust any pick down to 0 before submitting, keeping the $10 max in mind. Underdog pays any profit in bonus funds and returns your promo if the entry voids, but note that projections with payout modifiers don’t count.
Paul Reed hasn’t been pulling down many rebounds this season, averaging just over four per game. He’s missed some time due to injuries, and you’d have to go back to early December to find his last game with 9+ rebounds. I don’t see that changing tonight against the New York Knicks.
Meanwhile, Jaylen Brown has been crashing the boards at a high clip lately, recording seven or more rebounds in eight of his last 10 games and 15 of his last 20. Can Brown keep the streak alive and pull down seven or more boards against the Golden State Warriors?
