The Vice theme continued with the 2020–21 "City" uniform, this time featuring a pink and blue gradient and black letters. In the 2021–22 season, the Heat wore special "City" uniforms that mixed various uniform styles used by the team. The black-based uniform featured a mix of lettering taken from the Heat's previous and current uniform sets, including the throwback Floridians and Miami Vice "City" set. Players were allowed to choose their own number styles. A white version of this uniform served as its 2022–23 "City" uniform. Miami's 2021 "Earned" uniform (rewarded after making the 2020 NBA playoffs) marked the first time the team used yellow as a base color; previously it was only utilized as an accent color on the logo and uniforms. Letters were rendered in black with white trim, but red was not used at all in the uniform.

During that period, the Heat were eliminated three times by the Bulls, who would go on to win the NBA championship each time. After Jordan retired and the Heat's fall in the early 2000s, the rivalry cooled but slightly picked up when the Heat faced them in the first round of the 2006 NBA playoffs, which ended in a 4–2 Heat series victory and went on to win the NBA Finals. The Bulls would sweep the defending champion Heat in the first round the next season. The rivalry has intensified with the resurgence of the Bulls, and the emergence of Derrick Rose and the Heat re-signing Dwyane Wade (who
