The NBA, in its never-ending effort to get teams to take the regular season more seriously, instituted the Play-In Tournament back in 2020-21. The idea is simple: Give more teams an opportunity to make the playoffs, and even if they’re a sacrificial lamb to a 1-seed, they’re going to go for it. And outside of what the Dallas Mavericks pulled down the stretch last year, the idea has generally been a major success.
