Jaylen Wells Rebounds Prop is currently Over/Under 3.5 (+110/-145).
The money has been on the Under as it opened 3.5 @ -130 before it was bet down to 3.5 @ -145.
FACTORS THAT FAVOR THE OVER:
The Memphis Grizzlies have played at the 2nd-fastest pace-of-play in the NBA over the last 15 games.
The San Antonio Spurs have played at the 7th-fastest tempo in the NBA over the last 5 games, which should lead to increased plays for the Grizzlies.
FACTORS THAT FAVOR THE UNDER:
The Memphis Grizzlies rank as the 3rd-worst offensive rebounding offense in the NBA over the last 5 games (offensive rebounds maintain possession, and a lack of them may therefore eliminate extra chances for scoring and assists).
