CJ McCollum Rebounds Prop is currently Over/Under 3.5 (+123/-137).
The money has been on the Under as it opened 3.5 @ -122 before it was bet down to 3.5 @ -137.
FACTORS THAT FAVOR THE OVER:
The Wizards have played at the 3rd-most up-tempo tempo in the league this year.
The Wizards will likely see a spike in plays today from squaring off against the 3rd-speediest pace-of-play offense in the league over the last 5 games (the Timberwolves).
