Maybe it’s parity. Maybe it’s chaos.

Either way, the final day of the NBA’s regular season should be wild.

Oklahoma City, Minnesota and Denver all have a shot at No. 1 in the Western Conference. Every seed from No. 2 to No. 8 is up for grabs in the Eastern Conference. Sunday’s slate, with all 30 teams playing, will see nine seeds get decided, three first-round playoff matchups determined and three play-in matchups set as well.

“There’s so many possibilities and different things that can happen that just you kind of have to lock in to your team or you’ll drive yourself crazy watching other games and wishing and hoping,” Phoenix guard Devin Booker said. “So, either way, you’re going to match up with somebody and we have to be ready to do that.”

A primer for the final day:

WHAT WE KNOW

Boston is No. 1 in the East and has home-court advantage throughout the NBA playoffs. The Los Angeles Clippers are No. 4 in the West and will open the playoffs against No. 5 Dallas. And No. 9 Chicago plays host to No. 10 Atlanta in an East play-in elimination game on Tuesday or Wednesday.
