Detroit took the first game in October (119–113), while they both secured a win in the December 2025 series. Securing a 3–1 or 2–1 lead in the season series is vital for tiebreaker scenarios come April, especially with the Eastern Conference top four being so tightly packed. The Pistons currently hold a 4.5-game lead over the Celtics. A win for them on Monday would further reinforce their status as the #1 seed. However, a Boston victory would pull them within striking distance of the second-place Knicks and keep the pressure on the Pistons. Additionally, they are both in contrasting forms lately. The Pistons have won five of their last seven games, while the Celtics have lost three of their previous five. Before this matchup, the Detroit Pistons will take on the Indiana Pacers, while the Boston Celtics will face the Atlanta Hawks. Once your NBA predictions are in, make sure your TV is tuned to NBC Sports or Peacock for the tip-off at 7:30 p.m. ET.   Comparing Other Sportsbooks’ Offers for NBA Games Caesars Sportsbook’s promo offers you a lucrative start, but it isn’t the only game in town.
