Norman Powell Rebounds Prop is currently Over/Under 3.5 (-154/+120).
The money has been on the Over as it opened 3.5 @ -152 before it was bet up to 3.5 @ -154.
FACTORS THAT FAVOR THE OVER:
The Heat have played at the quickest pace in the NBA this year.
The Hawks have played at the most up-tempo pace-of-play in the NBA over the last 5 games, which ought to lead to more opportunities for the Miami Heat.
FACTORS THAT FAVOR THE UNDER:
The Miami Heat check in as the 8th-worst offensive rebounding offense in the league over the last 25 games (offensive rebounds maintain possession, and a lack of them can therefore eliminate further opportunities for scoring and assists).
