The Miami Heat's strength this season was their cohesive unit.
They had almost their entire starting lineup back from their Eastern Conference championship squad .
Even so, adjusting to new lineup rotations takes time.
The season-opening defeat on Wednesday to the Chicago Bulls hammered it home.
They had a hard time adjusting to everything being so different at first.
Coach Erik Spoelstra has been experimenting with various rotations and has added Tyler Herro and Caleb Martin to the starting lineup.
