For most of the 2025-26 season, Wembanyama's combined rebounds and assists prop has been priced just a tick above where he actually lands. Rithmm's models have tracked 21 instances of this prop this season, and the under has connected 13 times. That is a 61.9% hit rate built over a full year of tracked predictions.
For Game 7 at OKC, the models are flagging it again. The pick is Wembanyama Under 15.5 Rebs + Asts at +104.
Several independent data threads converge on this prop at once. At the position level, NBA centers going under on combined Rebs + Asts in near-even markets have hit at a 55.7% clip across 451 tracked bets, returning +9.1% over that sample. When the implied probability narrows to the 54-57% window, which is where this line is sitting, the hit rate holds steady at 56.4% across 117 bets. The specific line at 15.5 for this stat combination has gone under 30 times in 49 tracked instances, a 61.2% hit rate.
The month adds another signal. During May specifically, the Rebs + Asts under for NBA players has connected 35 of 56 times, a 62.5% win rate with a +19.0% return on investment. That seasonal pattern is one more thread pointing the same direction.
Then there is Wembanyama's own track record. His personal Rebs + Asts under is 13-8 this season, meaning the market has consistently set this line above where he actually finishes. Game 7 brings tighter defense, slower pace, and more structured possessions, conditions that typically press down on counting stats rather than inflate them.
The payout makes this pick more interesting. The models are flagging the under and you are getting better than even money to take it. At +104, there is value sitting right in the line.
The pick is Wembanyama Under 15.5 Rebs + Asts (+104) for Game 7 at OKC. Rithmm has this flagged now.
