The Miami Heat lost 124-116 against the Chicago Bulls on Thursday after rallying from a 25-point deficit in the first quarter.

Five key takeaways:

1. The Bulls’ strong start was too much.

Chicago’s 36-point opening quarter kept Miami from leading all game. After shaving four points off their halftime advantage, they lacked the offense to win. Because the Heat couldn’t match their scoring pace, Tyler Herro’s absence is more noticeable. Late December is his expected return.

2. Without Bam Adebayo and Haywood Highsmith, the Heat’s defense is their biggest vulnerability.

Charlotte’s weak offense made their defense irrelevant against the Hornets. The first quarter revealed Miami’s defensive shortcomings. In addition, Bulls big Nikola Vucevic scored 24 points, 12 rebounds, and 7 assists. They must learn to play without their top defenders, whether due to communication or ability.

3. Miami’s balanced оffensive failed.

The Heat were outscored offensively despite five players scoring over 15 points. Jaime Jaquez Jr. scored 22 points, while Jimmy Butler, Caleb Martin, and Kyle Lowry scored 54 points and 21 rebounds.

4. The Heat have trouble stopping backcourt scoring.

Terry Rozier scored 34 and 28 points in two games this week for the Charlotte Hornets. Similar issues plagued Chicago guard Coby White. White scored 26 points and 11 assists on 45% shooting.

5. Coach Erik Spoelstra made substantial early changes.

After a dismal defensive start, Spoelstra made changes. Jamal Cain and R.J. Hampton played in the first quarter. ιnjury-plagued Spoelstra and the Heat lack roster consistency. Health is key for playoff success.
