Karl-Anthony Towns Blocks Prop is currently Over/Under 0.5 (+135/-175).
The money has been on the Under as it opened 0.5 @ -170 before it was bet down to 0.5 @ -175.
FACTORS THAT FAVOR THE OVER:
The Grizzlies have played at the 5th-speediest pace in the NBA over the last 5 games without the home court advantage, which should lead to increased possessions for the Minnesota Timberwolves.
