A terrifying dream in which the dreamer experiences feelings of helplessness, extreme anxiety or sorrow.
That is how Dictionary.com defines nightmare.
Something we are all susceptible to and can strike at anytime. Even if you just won the NBA championship, employ the world's greatest player and have two perennial All Stars surrounding him.
Miami Heat coach Erik Spoelstra is not immune to nightmares.
He may not be kept up by the same feelings of coaching helplessness that Mike Dunlap could be in Charlotte, but he still has reasons to worry.
Lofty expectations are associated with coaching the NBA's most talented team. A team that, despite their talent, still does not include a legitimate NBA center.
Meanwhile, the second best center in the NBA now resides in the Eastern Conference. Miami's biggest rival out West just acquired the best one—along with a new point guard expected to make that center even more dominant than he ever was before.
The threat of injury is always there. Innate distractions unique to only his team also exist for Erik Spoelstra. An opposing point guard who's been a problem before could be even more of a problem this time around.
There's also that Hall of Fame coaching option available to step in should those expectations appear as if they won't be met.
At just that moment when things would seem they couldn't get any worse.
