Ja Morant and Steph Curry. Adding to the excitement of this year's postseason, there is no clear favorite. From the Brooklyn Nets to the Utah Jazz, the 2021 NBA Championship is completely up for grabs. Play-In Tournament Guidelines The rules for the 2021 NBA play-in tournament are simple. In each conference, the top six seeds are set and guaranteed playoff spots in the 16-team playoff bracket. Teams that finished anywhere seven and ten in their respective conferences are set to compete for the seventh and eighth seeds in each conference. The seventh seed plays the eighth seed and the ninth seed plays the tenth seed. The team that wins the game between the seventh and eighth seed will earn the seventh seed. Meanwhile, the loser of the seventh and eighth seed matchup will play the winner of the ninth and tenth seed play-in game. From there, the team that wins that game will earn the eighth seed. Actually, I lied. It's not all that simple. Watch the video above if any of this sounds confusing.
