Miami Heat vs. Boston Celtics bottom line: It feels like the book is out on the Heat now, with the obvious indication they’ve shifted as each preview the offense continues to spiral downward while the defense is climbing up the ladder.
That’s much more similar to the Heat of old than the initial iteration that began this season.
As for the Celtics, they remain a perimeter-heavy team that had turned a corner, but like all the seeds sitting third through ninth seeds, they are vacillating between stretches of great basketball mixed with mediocre showings.

Heat Celtics Free Pick: Heat +6.5
Here is my Heat Celtics free pick. Miami has struggled on the road (5-8) while the Celtics are 8-5 at home.
These squads are vastly different in their approach to offense, with Boston jacking up perimeter shots while the Heat will drive the middle of the court looking to score in the paint or at the rim. Whoever masters their objective will have the edge in this match.
Miami ranks second in perimeter defense holding teams to 33.2% which poses issues for the Celts who attempt 43.3 deep balls per game.
As much as the Heat are struggling, it’s unfathomable to me that the Celtics struggle to move the ball (see assists) or rebound well, yet they keep most games close.
Although they perform well at home and I like them to collect the win, I’ll take the points and the Heat to keep things close.
