Pascal Siakam Blocks Prop is currently Over/Under 0.5 (+174/-236).
The money has been on the Under as it opened 0.5 @ -235 before it was bet down to 0.5 @ -236.
FACTORS THAT FAVOR THE OVER:
The 6th-quickest tempo offense in the league over the last 20 games has been the Pacers.
The Cavaliers have played at the 3rd-quickest tempo in the NBA away from their home court this year, which should boost possessions for the Indiana Pacers.
