With one week to go in the NBA season, there is still plenty to be decided in terms of postseason seeding—with Wednesday’s schedule looming very big in several races. Here’s how things stack up now:

Western Conference No. 2 seed

Combatants : Thunder and Clippers.

Importance level : Huge . Nothing is guaranteed in the Western Conference, but if OKC and the Clippers get through the first round of the postseason, they would face each other in the conference semifinals, and whomever is the second seed would have homecourt. Both teams have a 32-7 home record, tied for second in the NBA.

Outlook : The Thunder hold a 2.5-game lead (three in the loss column) after Wednesday’s huge win over the Clippers. The Thunder close with two against New Orleans, a game at Indiana and at home against the Pistons. The Clippers get the Kings and Nuggets at home, but might have to win in Portland in the finale to move up.

Western Conference No. 7 and 8 seed

Combatants : Suns, Mavericks and Grizzlies.

Importance level : Big . It is entirely probable that there will be a 49-win team in the Western Conference that does not make the playoffs. That would be a tough blow to take for any team.

Outlook : The Suns continue to defy the odds and push toward the West postseason. Memphis went through a stretch of six games out of seven on the road and fell down badly, going 3-4 in that span. The Grizzlies got a huge win over the Heat at home on Wednesday to vault back into the mix. Dallas, meanwhile, is in the driver’s seat, with just three games (Spurs and Suns at home, and at Memphis to close) on the schedule. Win two of those three, and the Mavs are in.

Eastern Conference No. 3 and 4 seed

Combatants : Nets, Bulls and Raptors

Importance level : Consequential . Getting the No. 3 seed means facing a relatively easy and inexperienced first-round foe, either the Bobcats or the Wizards. Fall to No. 4, though, and it is likely you’ll get a dangerous Nets team in the opening round.

Outlook : The Nets probably have to close with wins in their last four games to have a chance to move up, and even then, they’d need stumbles from Toronto or Chicago. They can be penciled in at No. 5. That leaves Chicago and Toronto in a dead heat, each with four winnable games remaining on the schedule. But the Raptors have the softer path.

Eastern Conference No. 1 seed

Combatants : Heat and Pacers

Importance level : Diminishing . After chasing No. 1 all season, Pacers coach Frank Vogel now says he wants to rest his starters, letting the chance at No. 1 (and homecourt advantage all the way through the East playoffs) slip by. The Heat, too, will rest players, leaving open the question: If the two teams don’t care who’s No. 1, should we?

Outlook : The Pacers have two of three on the road, including Friday in Miami. Their only home game is against the Thunder. They lead the Heat by a half-game, and probably will hold the tiebreaker (even with a loss to Miami) because of an edge in conference record. So, though Vogel may be folding, the Pacers have a shot.

Eastern Conference No. 6 seed

Combatants : Bobcats and Wizards.

Importance level : Worthwhile . Though both the Heat and Pacers are struggling, you’d much rather be No. 6 in the East than No. 7. No. 6 means you’re likely to see Toronto rather than one of the two East elites.

Outlook : Sure, the West had Clippers-Thunder on Wednesday. But the East had Bobcats-Wizards. Bobcats-Wizards! Charlotte essentially needed to win this game in order to catch Washington, and they did. The two are locked up in a dead heat with the same record, but the Bobcats have the tiebreaker in hand.

Western Conference No. 5 seed

Combatants : Blazers and Warriors

Importance level : So-so . The Warriors still have to watch out for the Mavericks on their rear flank, but they have a chance to overtake Portland for the No. 5 seed, too. But that only wins them a matchup against the Rockets, which is no bargain — Golden State is 2-5 against Houston in the last two years.

Outlook : The Warriors have a legitimate chance, especially if they can win in Portland on Sunday. They probably will hold the tiebreaker over the Blazers (even with a loss to the Blazers) because of their conference record, but the Warriors’ big problem is that Portland’s next game is against Utah. The Blazers can probably hold onto their seed.

Eastern Conference No. 8 seed

Combatants : Knicks and Hawks.

Importance level : Yawn . The Hawks would much rather be in the lottery than in the playoffs, but the Knicks have refused to comply. They’re playing for the right to be first-round cannon fodder. Most interested: The Nuggets, who have the Knicks’ pick and would like it to be in the lottery.

Outlook : The Knicks trail Atlanta by two games in the loss column, and the Hawks have the tiebreaker advantage based on conference record. That means that even if the Hawks go 0-4 to close the year, the Knicks would have to go 3-1, with games against the Raptors (twice), plus the Nets and Bulls. And the Hawks have a game against Milwaukee, so don’t count on them going 0-4.
