The four teams at the top of ESPN.com's weekly NBA Power Rankings are pretty much interchangeable. So brace yourself for plenty of shuffling every Monday for the rest of the regular season.

This particular Monday is a prime example, with the Boston Celtics retaining the top spot as the NBA's first 40-win team ... but with Orlando vaulting from No. 4 to No. 2, leapfrogging No. 3 Cleveland with their home rout of the Cavs and dropping the Los Angeles Lakers to No. 4 after L.A. suffered the twin blow of a home loss to Charlotte and Andrew Bynum's scary knee injury.

Tune in Tuesdays to "NBA Fastbreak" on ESPN to see this week's U.S. Army Power Rankings. New York is the U.S. Army Team of the Week after posting three quality wins that have inched the Knicks to the brink of a top-15 spot for the first time all season.

2008-09 Power Rankings: Week 14
RANK (LAST WK)		TEAM	REC.	COMMENT
	1 (1)	Celtics	40-9	How much safer will they be taking a 12-game win streak into Thursday's home duel with the Lakers than they were toting a 19-game win streak into the Christmas showdown? Does it even matter since Bynum is out?
	2 (4)	Magic	36-10	Landing three All-Stars, routing Cleveland, reactivating Pietrus ... add it all up and last week might have been better for the Magic than the seven-day span in which they beat the Spurs, Lakers and Nuggets, all on the road.
	3 (3)	Cavaliers	37-9	As if the 22-0 record at home isn't gaudy enough, peep this: LeBron averaged 27.5 points, 9.6 boards and 8.2 dimes in January. The last guy to hit those heights for a full month was Larry Bird ... way back in 1987.
	4 (2)	Lakers	37-9	Those of you in Lakerland in such a rush to see Odom shipped out see now why your Lakers won't let him go until the summer. Who has the length and triangle knowledge to plug in for the fallen Bynum better than LO?
	5 (5)	Spurs	32-14	Pop sees 100 points on the scoreboard and says: "We're having too much fun." But maybe he shouldn't fight it, since his Spurs have merely won 30 games in a row -- that's 16-0 this season -- when they reach triple digits.
	6 (6)	Nuggets	31-16	The Nuggets can only hope Melo stays miffed about his All-Star omission for the rest of the month, because they're looking at a Spurs-like eight straight games on the road after San Antonio swings through Tuesday night.
	7 (9)	Trail Blazers	29-17	Since sweeping an early trip to Orlando and Miami, Portland has just one road win against a winning team ... way back on Nov. 30 in Detroit. Not that the Blazers' relative lack of road success is really hurting them.
	8 (7)	Rockets	29-19	It was right around this time last season that the Rockets launched that unforgettable 22-game winning streak. This season? We're guessing they'd probably settle for trotting out the same lineup 22 times in a row.
	9 (8)	Hornets	28-16	West is back from a back injury and back with the West All-Stars, but the Hornets really couldn't enjoy the moment. Not when they just became the first team with a winning record to lose at home to Golden State.
	10 (14)	Mavericks	27-19	The loudest voice in town against the idea of trading Josh Howard? It's Howard himself telling NBA TV "I know I might end up going somewhere" but insisting that the Mavs "don't need no changes right now."
	11 (10)	Heat	25-21	One small problem with our recent claim that D-Wade would have to merit MVP consideration if he could lead the ultra-thin Heat to 50 wins: Miami would have needed a 27-13 finish when we said it and is just 2-2 since.
	12 (12)	76ers	23-23	The Sixers sank all the way to 18-30 last season before rising to seventh in the East. The surge started much earlier this time -- Philly is 10-3 since its 13-20 start -- for you Brotherly Love denizens looking for silver linings.
	13 (13)	Suns	25-20	Anyone else getting the feeling that A) All-Star Weekend 2009 is going to be the high point of the Suns' season and/or B) All-Star Weekend 2009 is going to be remembered as Amare's farewell to the Valley of the Sun?
	14 (15)	Jazz	26-22	Anyone else getting the feeling that this just might not be Utah's year? We actually used that line five Mondays ago because of Boozer's knee op, but it's even more appropriate now with Kirilenko recovering from surgery, too.
	15 (11)	Hawks	27-20	You can't trash the Hawks for their 6-10 slump in January without noting that Horford has missed the past 11 games. The bigger issue: Woodson is losing this team, according to Page 74 in the latest issue of ESPN The Mag.
	16 (17)	Bobcats	19-28	Elaborating on the crack everyone's making about how the Lakers better hope they don't see the Bobs in the Finals: Charlotte is now one of only two franchises with a winning record against L.A. The other? Boston.
	17 (20)	Knicks	21-25	I'm not saying David Lee was blatantly snubbed by the East coaches. I'm just saying you can't scoff at a guy whose 35 double-doubles this season are second only to the 36 posted by someone named Dwight Howard.
	18 (18)	Pistons	25-21	Make that nine losses in 13 games, taking Detroit down to sixth in the East, with the ongoing pain in hopes of summertime gain conceivably getting worse before it gets better. July can't come soon enough.
	19 (19)	Pacers	19-29	The Pacers are saying Granger's knee trouble shouldn't keep him out of the All-Star Game. Don't think anyone needs to say what would happen to Indy's flickering playoff hopes if this is a problem he can't shake.
	20 (16)	Timberwolves	16-30	First Love gets snubbed from the rookie squad playing at All-Star Weekend. Then Jefferson gets snubbed from the West squad. Conclusion: Minnesota should have no problem with second-half motivation.
	21 (21)	Bucks	24-27	Can the Bucks really hang on to the No. 8 slot without our beloved Redd? Even with six teams chasing them? If Bogut's back holds up, along with that favorable second-half schedule and the new Villanueva ... maybe.
	22 (25)	Bulls	21-27	The short-term impact of Reinsdorf's outburst looks pretty good. But publicly branding this season a "disaster" is an outburst his rookie coach will hear about every day now. Can't see how that helps the cause.
	23 (22)	Nets	21-27	I had Devin Harris as an All-Star, too, so I'm not second-guessing the coaches. I'm just saying he's lucky they apparently made their minds up early, because the Nets' 3-9 swoon has dropped them below the Knicks.
	24 (24)	Warriors	15-33	The strangest part about the Warriors' two finest hours -- beating Boston at home on Dec. 26 and Friday's win in New Orleans -- is that those are Golden State's only two Ws all season where the game wasn't a shootout.
	25 (23)	Raptors	19-30	We state with a good degree of confidence that Raps fans needn't be worried about Bosh getting traded between now and the Feb. 19 deadline. Worrying about anything and everything else? Completely understandable.
	26 (26)	Thunder	11-37	Maybe a 7-8 record in '09 doesn't sound like much to you. Yet look what it's done for OKC: Durant is now seen as an All-Star snub victim, Westbrook finds himself in the ROY race and all those 9-73 fears are a memory.
	27 (30)	Kings	11-38	They're mentioned in lots of trade scenarios. They're also somehow 0-21 against the East, with only nine more chances to do something about that O-fer. Who says the Kings are giving us nothing to talk about?
	28 (29)	Wizards	10-37	I used to get a lot of flak for daring to suggest that Agent Zero wasn't the best handle for Arenas. Now I wonder: If Gil plays zero games this season, won't you blame at least some of that on bad nickname karma?
	29 (27)	Grizzlies	11-35	Our pal Sam Smith of Chicago fame was only teasing, sadly, when he saw the re-hiring of Lionel Hollins and recent re-acquisition of Steve Francis and wondered aloud about the Grizz possibly heading back to Vancouver.
	30 (28)	Clippers	10-37	This season is getting so painful, even with Baron and Camby back in the lineup, that Mike Dunleavy Jr. has almost as many wins in the 14 games he's played (seven) as his dad does with the Clips in 47 games coached.
