1. Golden State Warriors
2014 record: 67-15, 1st in West
Key additions: Jason Thompson
Key losses: David Lee
One thing to know: Roster continuity should keep the Warriors atop the NBA this season. They looked like they were in midseason form three weeks ago.
2. Oklahoma City Thunder
2014 record: 45-37, 9th in West
Key additions: Hired Billy Donovan (coach)
Key losses: none
One thing to know: Through the preseason, Kevin Durant hasn't shown any ill-effects from last year's foot surgeries, and new coach Billy Donovan has shown glimpses of how he'll mix up a previously stagnant offense.
3. Cleveland Cavaliers
2014 record: 53-29, 2nd in East
Key additions: Mo Williams, Richard Jefferson
Key losses: none
One thing to know: The Cavs finally re-signed Tristan Thompson, bringing back the entire core of last year's championship team. However, they're currently battling an injury bug that suggests it'll be another slow start to the season.

2014 record: 55-27, 6th in West
Key additions: LaMarcus Aldridge, David West, Ray McCallum Jr.
Key losses: Tiago Splitter, Cory Joseph, Aron Baynes

5. Houston Rockets
2014 record: 56-26, 2nd in West
Key additions: Ty Lawson, Marcus Thornton, Sam Dekker
Key losses: Josh Smith
One thing to know: The Rockets should benefit from more roster continuity and key additions like Ty Laweson, but Dwight Howard's health remains a concern.
6. Los Angeles Clippers
2014 record: 56-26, 3rd in West
Key additions: Josh Smith, Paul Pierce, Lance Stephenson, Cole Aldrich
Key losses: Matt Barnes, Spencer Hawes
One thing to know: The Clippers might have the deepest team on paper, but it's fair to wonder how a bench of Austin Rivers, Jamal Crawford, Lance Stephenson, Paul Pierce, and Josh Smith will mesh... and defend.
7. Atlanta Hawks
2014 record: 60-22
Key additions: Tiago Splitter, Tim Hardaway Jr.
Key losses: DeMarre Carroll
One thing to know: The Hawks lost one of the best perimeter defenders in DeMarre Carroll, but Thabo Sefolosha is back and healthy, and the Hawks addressed their problems on the glass by getting Spurs big man Tiago Splitter.
8. Toronto Raptors
2014 record: 49-33, 4th in East
Key additions: DeMarre Carroll, Cory Joseph, Bismack Biyombo, Luis Scola
Key losses: Lou Williams, Amir Johnson, Greivis Vasquez
One thing to know: Perhaps we're believing too much in preseason, but Skinny Kyle Lowry just averaged 22 points per game with 50% three-point shooting in less than 30 minutes per game. We're also buying what DeMarre Carroll is selling.
9. Memphis Grizzlies
2014 record: 55-27, 5th in West
Key additions: Brandan Wright, Matt Barnes
Key losses: Kosta Koufos
One thing to know: The Grizzlies still haven't added the necessary shooting that could bring this offense into the top-tier of the Western Conference.

Key additions: Bobby Portis, hired Fred Hoiberg (coach)
Key losses: none

11. Washington Wizards
2014 record: 46-36, 5th in East
Key additions: Jared Dudley, Alan Anderson, Gary Neal
Key losses: Paul Pierce
One thing to know: John Wall said his fitness level from last year wouldn't have helped him this year, hinting again that the Wizards are playing small and fast this season.
12. Miami Heat
2014 record: 37-45, 10th in East
Key additions: Justise Winslow, Amar'e Stoudemire, Gerald Green
Key losses: Shabazz Napier
One thing to know: Chris Bosh says the Heat can get a playoff seed just by showing up. It's possible in the weak East, but the Heat have so many injury and defensive concerns that they'll need to do more than just show up to prove they're one of the East's elite teams.
13. New Orleans Pelicans
2014 record: 45-37, 8th in West
Key additions: Hired Alvin Gentry (coach)

Key additions: Trey Lyles
Key losses: none
One thing to know: The Jazz were 19-10 with the NBA's best defense after the All-Star break last year. Can they maintain that success to fight for a playoff spot in the West?

Key losses: Brandon Bass
One thing to know: Like the Jazz of the East, the NBA world is waiting to see if the Celtics can carry a hot finish to last season into this year. The Celtics, for what it's worth, went 6-1 in preseason.
17. Milwaukee Bucks
2014 record: 41-41, 6th in East
Key additions: Greg Monroe, Greivis Vasquez, Chris Copeland
Key losses: Ersan Ilyasova
One thing to know: The Bucks got better on paper and have a year of experience under their belts, but can their offense produce enough points with so few shooters on the court?
18. Detroit Pistons
2014 record: 32-50, 12th in East
Key additions: Ersan Ilyasova, Marcus Morris, Stanley Johnson
Key losses: Greg Monroe
One thing to know: Andre Drummond is the star of the show this year, and in a new spaced-out offense, averaged 15 points and 12 rebounds per game in preseason.

2014 record: 50-32, 7th in West
Key additions: Wesley Matthews, Deron Williams, Zaza Pachulia
Key losses: Tyson Chandler, Rajon Rondo, Amar'e Stoudemire, Richard Jefferson
One thing to know: The Mavs went 0-7 in preseason, but the starting back-court of Wesley Matthews and Deron Williams are way ahead of schedule, which should be reason for optimism.
22. Sacramento Kings
2014 record: 29-53, 13th in West
Key additions: Rajon Rondo, Kosta Koufos, Marco Belinelli, Willie Cauley-Stein
Key losses: Jason Thompson, Nik Stauskas
One thing to know: The Kings went 5-1 in preseason, and ESPN's Marc Stein says NBA scouts are high on them. The Kings' multiple personalities in the locker room will be interesting to monitor at the first whiff of turmoil.

2014 record: 33-49, 11th in East
Key additions: Nicolas Batum, Jeremy Lin, Frank Kaminsky, Spencer Hawes
Key losses: Lance Stephenson, Bismack Biyombo
One thing to know: Not buying the 7-1 preseason, particularly with Michael Kidd-Gilchrist out for the year. The difference between the Hornets with Gilchrist in the lineup and out last season is alarming.

Key additions: Andrea Bargnani, Shane Larkin, Wayne Ellington
Key losses: Deron Williams, Mason Plumlee

2014 record: 30-52, 12th in West
Key additions: Emmanuel Mudiay, hired Mike Malone (coach)
Key losses: Ty Lawson
One thing to know: The Nuggets might not win many games, but Mike Malone knows a whole philosophical change in the organization is the biggest priority this season.
