New tournaments, roster shake-ups and casual wear -- lessons from the wildest NBA season on record

A season of prevent defense.

That's how one high-ranking NBA official described the 2020-21 regular season: a cramped, white-knuckle ride that saw one team transplanted 1,300 miles, 32 games postponed because of the coronavirus, winter storms and a rolling series of COVID-19 restrictions and countermeasures that NBA commissioner Adam Silver ominously dubbed "work quarantine."

The league brainstormed a series of on-the-fly modifications to standard operating procedures to manage many of the challenges -- health, logistical and financial, among others. Some originated in last summer's bubble in Orlando, and others came out of an endless series of video conferences between teams, the players' union and the league office.

Necessity, of course, turned out to encourage innovations. Now that the regular season has played out, which of them might stick around into the future?
