BOSTON (AP) — The latest Eastern Conference finals pairing between the Heat and Celtics will be a matchup that ultimately turns on the play stars like Jimmy Butler and Jayson Tatum. But Miami’s 123-116 Game 1 victory also showed how the tactical battle between rookie coach Joe Mazzulla and veteran counterpart Erik Spoelstra will also play a big factor. The Celtics dominated the first two quarters on Wednesday night before being outscored 46-25 in the third period – the most points they’ve allowed in any playoff quarter over the past 25 years.
