Memphis Grizzlies vs OKC Thunder preview

The Thunder and Grizzlies matched up four times this season, and OKC came out on top each time — and not just barely. They won by margins of 24, 13, 17 and 21 points, giving them an average victory margin of 18.8 points. It’s no surprise the sportsbooks have them heavily favored.

While OKC dominated the regular season, they enter this one off a lengthy layoff. Most of their starters sat out the final games, and this opener could be a rhythm check after more than 10 days off.

Even so, the Thunder's depth, which showed in every matchup against Memphis, gives them a huge edge.

In those four regular-season clashes, OKC averaged 125.0 points per game to Memphis’ 106.3. They controlled the boards (46.0 rebounds per game to Memphis’ 44.0) and moved the ball better (29.8 assists per game to 25.0).

Perhaps most striking: the Thunder shot 48.1% overall and 39.2% from deep while getting nearly 10 more shot attempts per game than the Grizzlies.

OKC thrives on generating offense through their league-best defense, and that could be the difference once again this afternoon.

Memphis showed heart during the play-in, but neither of those games featured a threat like OKC, especially with the Thunder coming in fresh and healthy.

The Grizzlies will be without forward Brandon Clarke due to a right knee PCL sprain, while GG Jackson is out for personal reasons. Jaylen Wells is also unavailable with a right wrist fracture, facial injuries, and remains in concussion protocol.

For the Thunder, Ousmane Dieng (left calf strain) and Nikola Topic (knee surgery) are the only players out. Neither impacts the rotation significantly — Dieng is a bench piece, and Topic was already ruled out for his rookie season.

Shai Gilgeous-Alexander dominated Memphis this year, averaging 36.3 points, 7.3 assist,s and 2.8 boards in their four meetings. Jalen Williams also put up strong numbers, averaging 19.8 ppg, 6.8 ap,g and 6.5 rpg in the season series.

Ja Morant appeared in two of the games and averaged 20.0 ppg, 6.5 apg, and 4.0 rpg. Jaren Jackson Jr. played in three and averaged 19.7 ppg, 3.3 rp,g and 3.3 apg.
