Having an incredibly deep team is a blessing for a head coach in any team sport.
The Miami Heat are a prime example of this. The Heat endured all kinds of injury misfortune this season. Jimmy Butler, Bam Adebayo, Kyle Lowry, and Tyler Herro played in 57 games, 56 games, 63 games, and 66 games this season respectively. Before the season started, many experts and fans alike predicted the Heat finishing anywhere from the 3rd-6th seed in the East this season and that was with the assumption that their top players would play regularly. Given that none of the top four players on the team played a significant number of games this season, it is nothing short of miraculous that the Heat finished as the 1st seed in the East.
