1. Atlanta Hawks (Record: 40-8; last week: 1): Atlanta was 17-0 in January and has won 19 straight games, but next are games against New Orleans, Washington, Golden State and Memphis.
2. Golden State Warriors (Record: 37-8; last week: 2): The Warriors visit the Hawks on Friday for what should be a dynamite matchup.
3. Memphis Grizzlies (Record: 35-12; last week: 3) Even with six straight wins and nine of 10 overall, the Grizzlies are still three games behind the Warriors for the top spot in the West.
4. Los Angeles Clippers (Record: 33-15; last week: 5): Western Conference All-Star point guard Chris Paul is averaging 20.6 points in his last five games while shooting 55.4 percent from the field.
5. Houston Rockets (Record: 33-15; last week: 4): The Rockets are surprisingly 11-5 without center Dwight Howard this season. He is out again indefinitely with a right knee injury.
6. Cleveland Cavaliers (Record: 29-20; last week: 10): The Cavaliers have won 10 straight games, winning by an average of 12.9 points while holding foes to 42 percent shooting.
7. Toronto Raptors (Record: 33-15; last week: 11): Toronto has won a season-high six straight games and are three wins from tying the longest winning streak in franchise history.
8. San Antonio Spurs (Record: 30-18; last week: 7): Spurs coach Gregg Popovich is three victories from 1,000 career wins and in typical fashion is shying away from any spotlight.
9. Portland Trail Blazers (Record: 32-16; last week: 6): Since not making the All-Star team, Damian Lillard has missed 27-of-39 shots the past two games, including 17-of-19 3-pointers.
10. Dallas Mavericks (Record: 32-17; last week: 8): Guard Rajon Rondo has an orbital fracture in his left eye and a nasal fracture and is out indefinitely.
11. Washington Wizards (Record: 31-17; last week: 9): All-Star John Wall has played in 180 consecutive games, but migraine headaches have his status in question for Monday night’s game against Charlotte.
12. Phoenix Suns (Record: 28-21; last week: 13): The Suns would like to trade reserve forward-center Miles Plumlee, but are not getting much interest, a source told Yahoo Sports.
13. Chicago Bulls (Record: 30-19; last week: 12): The drama between Bulls management and coach Tom Thibodeau seems similar to the San Francisco 49ers’ situation with ex-coach Jim Harbaugh.
14. New Orleans Pelicans (Record: 25-22; last week: 14): All-Star forward Anthony Davis is expected to be back against Atlanta on Monday after being out with a left groin strain.
15. Milwaukee Bucks (Record: 25-22; last week: 16): So why didn’t the Knicks re-sign Bucks forward Kenyon Martin during the offseason? New York didn’t think he fit its new triangle offense.
16. Oklahoma City Thunder (Record: 23-24; last week: 15): As crazy as it sounds, we’re now to the point where it doesn’t appear to be a given that the Thunder will make the playoffs.
17. Miami Heat (Record: 21-26; last week: 17): Heat center Hassan Whiteside had a breakthrough January, averaging 13 points, 10.6 rebounds and 3.4 blocks per game.
18. Charlotte Hornets (Record: 20-27; last week: 19): The Hornets are 4-1 without guard Kemba Walker, who is expected to be out at least six weeks after knee surgery.
19. Denver Nuggets (Record: 19-29; last week: 20): While the Nuggets have had their share of injuries, guard Ty Lawson perhaps best described his team as “consistently inconsistent.”
20. Utah Jazz (Record: 17-30; last week: 22): It’s good to see that the Rocky Mountain Revue summer league will be returning to Salt Lake City. It was last held in 2008.
21. Sacramento Kings (Record: 17-29; last week: 24): The Kings are still actively trying to acquire an athletic big man to play alongside All-Star center DeMarcus Cousins, a source said.
22. Brooklyn Nets (Record: 18-28; last week: 21): Keep an eye on the struggling Nets, losers of four straight, as the Feb. 19 trade deadline approaches. They could be the most active team.
23. Detroit Pistons (Record: 18-30; last week: 18): The Pistons are 1-3, including a 20-point loss to Philadelphia, since losing guard Brandon Jennings for the season because of a torn Achilles’ tendon.
24. Boston Celtics (Record: 16-30; last week: 23): It’s unlikely the Celtics will be able to trade veteran forward Tayshaun Prince before the trade deadline, a source said.
25. Indiana Pacers (Record: 17-32; last week: 25): Even if Paul George could return from a severe leg injury this season, would it be worth it if struggling Indiana can’t even complete for a playoff spot?
26. New York Knicks (Record: 10-38; last week: 28): A source said the Knicks are actively trying to unload guard Jose Calderon’s contract. Calderon is owed $7.4 million in 2015-16, and $7.7 million in 2016-17.
27. Orlando Magic (Record: 15-35; last week: 26): The Magic could be waiting to fire coach Jacque Vaughn at the All-Star Break to give the team more time to adjust to the change, a source said.
