Current playoff picture

This is the Too Long; Didn't Read version. If the season ended right this second, here are your first-round matchups. Teams in ALL CAPS are locked into their seeds.

WARRIORS (1) vs. Pelicans (8) BLAZERS (4) vs. Rockets (5) Houston has home court advantage Spurs (2) vs. MAVERICKS (7) Clippers (3) vs. Grizzlies (6)

Standings

If you have a better record than the next team in line, tiebreakers don't matter. There is one quirky thing here: division winners cannot be seeded below No. 4, but division winners do not get home court advantage against teams higher than them in the standings in any case.

Here's the major jumble from the No. 2-6 spots.

2. Spurs       55-26  --
3. Clippers    55-26  --
4. Blazers     51-30  4
5. Rockets     55-26  --
6. Grizzlies   54-27  1

And here's the race for No. 8.

8. Pelicans    44-37  --
9. Thunder     44-37  --

Magic numbers

New Orleans' magic number to clinch the No. 8 seed is 1 (combined wins and Thunder losses)

Oklahoma City's magic number to clinch the No. 8 seed is 2 (combined wins and Pelicans losses)

Tiebreaker Situations

If teams finish tied in the standings, this is how berths and seeds will be determined.

MEMPHIS over Houston: The teams split the season series. But the Rockets can no longer finish with a better division or conference record than the Grizzlies, and Memphis' record against West playoff teams (regardless of whether OKC or New Orleans make it) is guaranteed to be better.

MEMPHIS over San Antonio: The teams split the season series. San Antonio cannot finish with a better divisional record and the Grizzlies have clinched a better record against the West.

SAN ANTONIO over Houston (head to head)

SOUTHWEST CHAMP over Los Angeles (division winner)

LOS ANGELES over San Antonio and Houston*: The Clippers split these season series, but neither the Spurs nor Rockets can finish with a better record against the West. This does not apply to whichever of the Spurs and Rockets win the Southwest. It does apply if Memphis wins the Southwest.

NEW ORLEANS over Oklahoma City (H2H)

Unsettled Tiebreakers

Memphis-Los Angeles: The teams split their season series. If Memphis wins the Southwest, it wins this tiebreaker. Otherwise, L.A. needs to sweep its schedule or have Memphis lose to Golden State (4/13) to get the tiebreaker.

Head-to-head data
