Maybe the NBA should hold its playoffs in a bubble all the time.

It is basketball distilled to its essence – five-on-five in a random gym.

“At the end of the day, it's just guys playing in between those lines and who executes better and who plays the whole 48 or 53 or 58 minutes, or however long it takes, better,” Celtics coach Brad Stevens said.

Of course, it's not feasible to have playoffs in a bubble every season. But hear me out: the bubble has produced compelling and unpredictable basketball.

I realize that happens in other playoff seasons, too. But the bubble has magnified that with no home court, no fans, no travel – just two teams playing basketball at a neutral site.

“The level of basketball has been great,” Stevens said.

Perhaps even better basketball than a regular playoff?

Neither the No. 1 seed nor No. 2 seed reached the Eastern Conference finals for the first time since 1984, when the league expanded its playoffs.
