Mark Williams Rebounds Prop is currently Over/Under 10.5 (+130/-170).
The money has been on the Over as it opened 9.5 @ -130 before it was bet up to 10.5 @ +130.
FACTORS THAT FAVOR THE OVER:
The Hornets have been the 5th-best offensive rebounding offense in the league when playing at home this year (offensive rebounds maintain possession and can therefore create new opportunities for scoring and assists).
