Al Horford Assists Prop is currently Over/Under 2.5 (-167/+125).
The money has been on the Under as it opened 3.5 @ -143 before it was bet down to 2.5 @ +125.
FACTORS THAT FAVOR THE OVER:
The Celtics check in as the 9th-best offensive rebounding offense in the league over the last 25 games (offensive rebounds maintain possession and may therefore produce added opportunities for scoring and assists).
Al Horford will have the benefit of the home court advantage in this contest. Playing in your home city usually raises player performance across the board.
FACTORS THAT FAVOR THE UNDER:
The 2nd-most sluggish pace team in the NBA over the last 15 games has been the Celtics.
The Heat have played at the least up-tempo tempo in the NBA while traveling this year, which should lead to fewer possessions for the Boston Celtics.
