The Trail Blazers chances for home court advantage in the first round of the NBA playoffs took a major hit Thursday with Portland's loss to Golden State. But with less than a week remaining in the regular season there is still plenty left to be determined in the Western Conference.

The Golden State Warriors have secured the top seed and home court advantage. Dallas on Wednesday virtually guaranteed itself the 7th spot with a win over Phoenix, which eliminated the Suns from the playoffs. The Blazers look to be set in the fourth seed, but will almost certainly begin the postseason on the road.

As for the other five seeds in the West, it's going to be a fun final five days. Just a half game separates No. 2 and No. 6.

The San Antonio Spurs beat the Houston Rockets on Wednesday to pull within a half game of the Rockets and Memphis Grizzlies. The Spurs are tied record-wise with the Los Angeles Clippers at 53-26, but are stuck in sixth place because the Clippers hold the tiebreaker due to a better record against Western Conference teams.

Memphis (53-25) is currently in second despite having an identical record as third-seeded Houston. The Grizzlies and Rockets split the regular season series, but the Grizzlies have an edge thanks to the superior record against Southwest Division foes.

The Blazers (51-28) are the fourth seed, but are currently slated to open the playoffs on the road against the fifth-seeded Clippers (53-26). Winning the Northwest Division guaranteed the Blazers a top-four seed, but not home court advantage, which is determined first by overall record. If the Blazers and a non-division winner finish with the same record as the four and five seeds, Portland would get home court advantage thanks to the division crown.

The New Orleans Pelicans (42-36) hold the final playoff spot because of a 3-1 series lead over the Oklahoma City Thunder (42-36). The Pelicans have a brutal final week, so if they do end up with a postseason berth they will have earned it in April.

Friday's games should offer a little more clarity.

The Pelicans and Thunder both have home games on Friday against Phoenix and Sacramento respectively. The Spurs face the Rockets in Houston on Friday night. A win would give San Antonio the head-to-head tiebreaker and propel the reigning champs into the No. 3 spot. Houston would drop to sixth with the loss. The Rockets would have the same record as Los Angeles, but the Clippers hold the tiebreaker over the Rockets because of a better record against the West.

The Grizzlies are on the road to face the Jazz on Friday and then have a huge game against the Clippers in Los Angeles on Saturday. When the dust settles Sunday morning we'll likely have a good idea where everyone is headed. Enjoy the next 48 hours.
