When one thinks of Miami's roster, it's not hard to envision why rim protection is an issue at times. Bam Adebayo does a lot of good things on the defensive side, but he's not a shot blocker. Kel'el Ware started to come along during the back half of last year, but Miami doesn't really have a second big man to rotate for him.
The biggest one: Head coach Erik Spoelstra is planning to play small. Potentially really small. Yes, the Heat went from (an injured) Highsmith to bringing back Smith in part because it fit with their plan to get under the luxury tax. They also didn't need to cut payroll. They have until the end of the 2025-26 season calendar to shave dollars and cents off the bottom line.
