NBA general managers made a number of people happy this summer: moving companies, real estate agents, building contractors, and Nets and Kings fans.

From the day before the NBA Draft on June 25 when the Wizards sent Courtney Alexander to New Orleans for a 2002 first-round pick, to Oct. 3 when the Spurs acquired Mengke Bateer from the Pistons, this offseason has been a moving experience for a number players.

By making numerous high-profile trades, and a pair of key free agent signings, NBA GMs took the vacation out of summer vacation. Two teams in particular -- the New Jersey Nets, last season's Eastern Conference champs, and the Sacramento Kings, who fell to the Lakers in the Western Conference Finals -- went offseason shopping for tall gentlemen who could possibly neutralize the supernatural force that is Shaquille O'Neal.

Here's a look back at the "biggest" transactions made this summer.

Nets Move A Mountain

The Nets made the first significant move when they sent forward Keith Van Horn and center Todd MacCulloch to the Sixers on Aug. 6 for Dikembe Mutombo. Nets GM Rod Thorn, who will forever be known as the man who drafted Michael Jordan, believed bringing Mt. Mutombo to the swamps of Jersey would provide the Nets with rock-solid defense in the post.

“In bringing Dikembe to New Jersey, we have added a perennial All-Star to our roster,” said Thorn. “He is a four-time NBA Defensive Player of the Year who is one of the leading rebounders and shot blockers in the NBA. Dikembe’s presence in the middle will strengthen our interior defense and his attributes fit in well with our overall style of play.”

While shoring up the defense with the trade, the Nets improved their bench through free agency when they signed point guard Chris Childs to spell Jason Kidd, and forward Rodney Rogers to replace some of the points Van Horn took with him to Philly.

"This team will be a lot better with Mutombo, me and Childs," Rogers said after he signed. "You have guys who want to win and who play hard on the floor. I think we give us the firepower we need and the defensive presence where we need to be tough at."

Kings Think Clark is the Keon to Topping the Lakers

Another team that believed it needed a defensive presence to combat Shaq is Sacramento. With his team close to making the NBA Finals last season, Kings GM Geoff Petrie went out and plucked the best free-agent big man from the bunch when he signed Keon Clark on Aug. 14. Kings fans, and newspaper columnists, were breathless when describing Vlade Divac's new backup.

"Divac, whose mobility and versatile offensive skills enable him to occupy Shaq more than any other center," wrote Ailene Voisin in the Sacramento Bee, "gains an assist from Clark, a natural lefty whose inside game is a cornucopia of acrobatic drop shots, spinning, one-handed monster dunks, explosive follow shots and weakside defense that results in a healthy dose of blocked shots and deflections."

The excitement was still palpable in Northern California when the Kings received more good news two days later when point guard, and restricted free agent, Mike Bibby decided to stay with the Kings.

"With the addition of Keon Clark and the signing of Mike, I think this is one of the better teams that has been assembled," Gavin Maloof said while the ink on Bibby's contract was still wet. "We're putting it up against anybody."

Clippers Get Miller to Do the Dishing

While the Kings and Nets must be considered the favorites to dethrone the Lakers, plenty of teams prepared themselves to challenge the champs, including the across-the-Staples-Center-hallway rival Clippers.

Overflowing with precocious players, the Clippers' GM Elgin Baylor acquired Andre Miller, the league's leader in assists last season, from the Cavaliers to feed that young talent. In return, the Clippers sent the exciting Darius Miles east.

"The one thing that makes this both easier and exciting is a situation like this when you are getting a proven player in return who has established himself as one of the top five point guards in the NBA," Baylor said.

Pistons Get an Overhaul

The Pistons, former champions themselves, may have taken the biggest leap of faith in the offeseason.

After winning the Central Division and 50 games, Detroit GM Joe Dumars sent the Pistons' leading scorer, Jerry Stackhouse and two others to the Wizards for Richard Hamilton, Hubert Davis and Bobby Simmons, who was later cut and re-joined the Wizards.

"I see us having tremendous depth on our team," Dumars told the Detroit Free Press on Sept 13, two days after the trade. "You can stand pat and say, well, we had success last year and it'll automatically carry over into next year. That's just not the case. Unless you're the Lakers and you're world champions, you're probably not looking to add a whole lot, and they still made trades and drafts and added people."

Dumars also added free agent point guard Chauncey Billups to share time with Chucky Atkins.

More Moves in the East

While Dumars was shoring up his backcourt, many vertically challenged Eastern Conference teams tried to get bigger. With the acquisition of Vin Baker on July 22, the Celtics added a post player who can score when motivated. And Baker says he will be focused this season.

"I grew up here in New England, Connecticut, about an hour and 45 minutes away," Baker said. "I have an opportunity to play in front of my family, and I also have an opportunity to play for one of the (most storied) franchises in all of sports, the Boston Celtics.

"Growing up in this area and being a fan of the Celtics, with those things combined and how they are a very good young team made it to the Eastern Conference finals last year. With those things combined, I think it makes for great situations being home and playing for the Celtics."

One of Baker's former teammates in Milwaukee, Glenn Robinson, also hit the road. The Bucks sent Robinson, the No. 1 overall pick in the 1994 Draft and the franchise's second-leading scorer, to Atlanta for Toni Kukoc and a 2003 first-round pick. The Hawks, who have guaranteed season ticket holders that the franchise would make the playoffs this season or they would get their money back, believe Robinson will help put them in the postseason for the first time since the 1998-99 season.

"He addresses one of our specific weaknesses, which was the perimeter game,'' Hawks general manager Pete Babcock said. "We're sorry to see Toni Kukoc go, he was an integral part of our rebuilding process. But we had to give up something to get a player of Glenn Robinson's caliber."

The Knicks felt they had to make a similar sacrifice. It's appropriate that in the financial capital of the world, New York Knicks general manager Scott Layden opened the markets with a blockbuster trade on Draft Night 2002. The Knicks sent Marcus Camby, Mark Jackson and the draft rights to Maybener "Nene" Hilario to Denver for the post player the Knicks felt they needed in Antonio McDyess and the draft rights to Frank Williams.

"I feel it’s one of the best sports cities in the world. I couldn’t pass up this opportunity; it’s a great city," McDyess said. "I’m a country boy but still, I think I can adapt to anything. I’ve got seven years in the league and it just looked like a great opportunity for me to come up here and try to contend to be one of the best teams in the East. "
