Payton Pritchard Assists Prop is currently Over/Under 3.5 (+115/-145).
The money has been on the Under as it opened 3.5 @ -140 before it was bet down to 3.5 @ -145.
FACTORS THAT FAVOR THE OVER:
The Boston Celtics rank as the 5th-best offensive rebounding offense in the league over the last 24 games on the road (offensive rebounds maintain possession and may therefore lead to added opportunities for scoring and assists).
