NBA Preview Wednesday Night via BetMGM

The Golden State Warriors are set to face off against the Boston Celtics on March 18, 2026, at 07:00 PM EDT. As both teams approach the final stretch of their 68-game campaigns thus far, the Boston Celtics are firmly positioned as a winning squad (45-23), sitting comfortably in second place in the Eastern Conference standings. Meanwhile, the Golden State Warriors (33-35) currently occupy the ninth spot in the Western Conference, fighting through a challenging, injury-riddled season but coming in hot after snapping a five-game skid.

Odds as of March 18, 2026 from MGM.

The Boston Celtics enter this matchup as heavy home favorites, laying 12.5 points, and for good reason. It goes without saying that Boston is an absolute wagon; they allow just 107.1 points per game and hold opponents to a low 44.1% shooting from the field. Their offense handles its business efficiently as well, averaging 114.30 points per game. Jaylen Brown is enjoying a career year, and the return of Jayson Tatum earlier this month from a torn Achilles injury has skyrocketed the Boston Celtics’ futures prices in the championship market.

On the other side of the court, the Golden State Warriors’ defense has been far more porous, surrendering 114.40 points per game. Head Coach Steve Kerr recently reached his 600th career win, making him the winningest coach in franchise history, but he is currently navigating a brutal injury report. The Warriors are missing Stephen Curry (knee), Jimmy Butler (out for the season with a torn ACL), Seth Curry (groin), Moses Moody (wrist), and Al Horford (calf), while Quinten Post is questionable.

Despite the missing pieces, the Warriors are at least getting some relative health back. Kristaps Porzingis makes his highly anticipated return to Boston after winning a 2024 championship with the Boston Celtics, giving the Golden State Warriors a unique emotional edge.
