Norman Powell Rebounds Prop is currently Over/Under 3.5 (-107/-123).
The money has been on the Over as it opened 2.5 @ -174 before it was bet up to 3.5 @ -107.
FACTORS THAT FAVOR THE OVER:
The Heat have played at the most up-tempo tempo in the league this year.
The New York Knicks have played at the 10th-most up-tempo pace-of-play in the league over the last 5 games at home, which should raise opportunities for the Miami Heat.
FACTORS THAT FAVOR THE UNDER:
The Miami Heat rank as the worst offensive rebounding offense in the NBA over the last 10 games (offensive rebounds maintain possession, and a lack of them can therefore reduce additional opportunities for scoring and assists).
