With Fab Melo dealt to the Grizzlies  Thursday, the Celtics  have already moved on from a player they selected 22nd overall in the 2012 NBA draft. In honor of that move, here is a look at all of the Celtics’ first-round picks under Danny Ainge and how they worked out for the club.
Marcus Banks (13th overall) ‘ The Celtics traded up to acquire Banks, dealing the 16th and 20th overall picks (Troy Bell and Dahntay Jones) for him and the 27th overall pick Kendrick Perkins . Banks was a disappointment with the Celtics, and only played only five games in three seasons with Boston before being traded along with Mark Blount, Ricky Davis , Justin Reed and two second round picks for Dwayne Jones, Michael Olowokandi , Wally Szczerbiak , and a 2009 first round pick. Banks last played with the Raptors ‘ his fifth team in eight years in the league ‘ in 2010-11, when he averaged 2.0 points in 7.3 minutes per game.
Kendrick Perkins (27th overall) ‘ Perkins, a center project out of high school, was the better half of that draft day trade and became the Celtics starting center in 2006-07. He used his strong defensive play to help the Celtics to an NBA Championship in 2008, and averaged 10.1 points and 7.6 rebounds in 2009-10. Perkins was traded with Nate Robinson  to the Thunder for Jeff Green , Nenad Krstic , cash and a 2012 first round pick ‘ which turned into Melo.
Al Jefferson  (15th overall) ‘ Jefferson was supposed to be the big man of the future, and was one of the Celtics top players in 2006-07 when he averaged 16.0 points and 11.0 rebounds in 33.6 minutes per game. Jefferson was the centerpiece in the package that the Celtics sent to Minnesota to acquire Kevin Garnett . Since then, Jefferson has been one of the best centers in the league with the Timberwolves  and the Jazz . Jefferson signed a three-year deal worth an estimated $41 million with the Bobcats  this offseason.
Delonte West  (24th overall) ‘ West had success with the Celtics early in his career, when he started at guard for Boston between 2005-07. West was a part of the trade that landed the Celtics Ray Allen  though, and was later dealt to the Cavaliers  where he started for a little over one season. West had brief stints with the Celtics and Mavericks between 2010-12, but did not play in the league last season.
Tony Allen  (25th overall) ‘ Allen has consistently been a strong defensive guard throughout his career, and helped the Celtics to the 2008 championship when he spent time guarding Kobe Bryant  and Lebron James . Allen signed with the Grizzlies  as a free agent in 2010 and started all 79 games that he played last season.
Gerald Green  (18th overall) ‘ Green was good for a few highlight dunks, but he has not made a real impact in the league as a small forward/shooting guard. Since being included in the Garnett trade, Green has spent time with five different teams. He did not play in the league in the 2009-10 or 2010-11 seasons, but made a nice comeback with the Nets  in 2011-12 when he averaged 12.9 points in 25.2 minutes per game.
The Celtics traded their first round pick (Randy Foye ‘ 7th overall) along with Dan Dickau and Raef LaFrentz to the Portland Trail Blazers for Sebastian Telfair , Theo Ratliff  and a 2008 second round pick. Telfair, who was the major piece in the trade, only spent one season with the Celtics before being included in the trade for Garnett.
The Celtics traded their first round pick (Jeff Green ‘ 5th overall) along with West and Szczerbiak for Allen. Ainge re-acquired Green in a trade for Kendrick Perkins and averaged 12.8 points and 3.9 rebounds in 27.8 minutes per game last season.
J.R. Giddens (30th overall) ‘ Giddens spent two seasons with the Celtics organization and only played in 27 games before being traded alongside Eddie House , Bill Walker  and a 2014 second round pick for Marcus Landry and Nate Robinson. Giddens last played in 2010 with the Knicks, when he averaged 4.1 points in 12.7 minutes per game.
The Celtics had included their pick in the trade for Garnett. The Timberwolves selected Wayne Ellington with the pick.
Avery Bradley  (19th overall) ‘ Bradley started out slow, only averaging 5.2 minutes per game in 31 games his rookie season. However, he has emerged as a very good defensive guard in his second and third seasons as a Celtics, and was a starter for Boston in 2012-13. He averaged 9.2 points and 1.3 steals in 28.7 minutes per game last season and is slated to start again for the Celtics this upcoming season.
JaJuan Johnson  (27th overall) ‘ Johnson was acquired in a draft-day trade for Marshon Brooks and a second round pick, and only spent one season with the Celtics before being dealt in a three-team deal that landed Boston Courtney Lee . Johnson did not play in the NBA last season.
Jared Sullinger (21th overall) ‘ Sullinger averaged 6.0 points and 5.9 rebounds in 19.8 minutes per game in his rookie season before missing the rest of the season with a back injury. The Ohio State product started five games last season.
Fab Melo (22th overall) ‘ Melo averaged 1.2 points and 0.5 rebounds in six games with Boston last season before being traded along with cash for Donte Green Thursday.
