The first "Big Three" wasn't in Miami, where LeBron James, Dwyane Wade and Chris Bosh teamed up to win two titles in four years with the Heat.

No, the first modern trio of superstars to join together to try to win a championship came in Boston, where Paul Pierce, Kevin Garnett and Ray Allen joined forces prior to the 2007-08 season.

The move immediately paid off, as the Celtics finished the year with an impressive 66-16 overall record and cruised through the playoffs, knocking off the rival Los Angeles Lakers in six games in the NBA Finals.

Coach Doc Rivers, who led the 07-08 Celtics to their 17th title in franchise history, is now coaching the Los Angeles Clippers after spending 2004 through 2013 in Boston.

Here's what the rest of the starting five from that year's Celtics squad, along with some key bench players, are up to now.

Rajon Rondo

As good as Pierce, Allen and Garnett were, the Celtics were led by Rondo in a lot of ways. The mercurial point guard had a breakout season in 2007-08, averaging 10.6 points, 5.1 assists and 4.2 rebounds a night while guiding the Boston offense.

Rondo would play five productive seasons in Boston before injuries and ineffectiveness led to him being shipped off to Dallas during the 2014-15 season.

Now, he's toiling away for the Chicago Bulls, where he's averaging only 7.8 points a night. He's also gotten into a couple of high-profile spats with both his coach and his teammates.

Ray Allen

When Ray Allen left the Celtics to join LeBron James and the Miami Heat following the 2011-12 season, causing a rift among the 2007-08 Celtics squad.

Though Allen averaged 17.4 points during the title-winning season, he hasn't been invited to the reunion that is being planned this offseason for that year's Celtics team (though Leon Powe is working to change that).

With 2,973 career three-pointers made, Allen is the NBA's all-time leader in that statistic. There have been rumors of him coming out of retirement in recent years, but having been out of the league for three years now, it's likely that we've seen the last of one of the best shooters ever to play the game. 

Paul Pierce

Pierce was entering his 10th season with the Celtics when he finally got the championship-level help he needed.

The 07-08 Celtics were still Pierce's team, though, as he led Boston with 19.6 points a night. He also averaged 5.1 rebounds and 4.5 assists per contest.

Since leaving the Celtics after the 12-13 season, he's played for the Brooklyn Nets (landing the Celtics a boatload of draft picks in that trade), the Washington Wizards and is now in his second season with the Clippers. He'll retire at the end of this season, but he'll always be remembered as one of the all-time great Celtics.

Kevin Garnett

Garnett brought the intensity and the will to win to Boston in a massive trade prior to the 07-08 campaign.

He averaged 18.8 points and 9.2 rebounds a night for the title-winning squad and, along with the next guy on this list, provided the intimidation factor that had been missing, making the Celtics a team opponents feared.

Garnett retired following the 2015-16 season (which he spent with the Minnesota Timberwolves, who drafted him back in 1995) and is now an NBA analyst for TNT.

Kendrick Perkins

Perkins played the role of enforcer for the 2007-08 Celtics, giving them a powerful post presence and anchoring the team's defense.

In 2007-08, he scored 6.9 points, grabbed 6.1 rebounds and blocked 1.5 shots per game while starting a career-high 78 games.

After leaving Boston during the 2010-11 season, Perkins played for the Thunder, Cavaliers, Mavericks and Pelicans, but is currently out of the NBA. He's attempting to make a comeback, though, and may land with a team before the 2017-18 campaign kicks off this fall.

James Posey

Posey only spent one season with the Celtics, but made the most of it, leaving town with an NBA championship ring. He averaged 7.4 points and 4.4 rebounds while playing 24.6 minutes a night coming off the bench.

Posey, who also won an NBA title with the 2006 Miami Heat, added a third ring to his collection last year as an assistant coach for the Cleveland Cavaliers. He still holds an assistant position on Tyronn Lue's Cavaliers staff.

Eddie House

House was a clutch player off the bench for the Celtics during their title run, hitting several big shots late in the season and in the playoffs. For the year, he averaged 7.5 points in 19 minutes a game.

Currently, House is living in Arizona, where his son Jaelen is a star basketball player for Shadow Mountain High School.
