After ten games, relying on point differential, the 2020 NBA Playoff line-up looks like: 

--Eastern (for sure): Boston Celtics; Milwaukee Bucks; Toronto Raptors; Miami Heat; Philadelphia 76ers; Indiana Pacers

--Eastern (maybe; 2 spots left): Cleveland, Orlando, Brooklyn, Detroit

--Western: Los Angeles Lakers; Denver Nuggets; Houston Rockets; LA Clippers; Utah Jazz; Phoenix Suns; Dallas Mavericks; Oklahoma City Thunder


--Western (maybe, but probs not): Minnesota, San Antonio, Portland (most likely: MN to replace OKC)
