Boston's braintrust has their work cut out for them.
Boston swapped a veteran head coach for a young, college standout. The Celtics moved their veteran stalwarts for a group of talented role players and a stockpile of draft picks.
Ahead are the pros and cons of each and every move Boston made this summer.
Brad Stevens faces a tough first year.
Former Butler head coach Brad Stevens will take over the same position with the Boston Celtics following Doc Rivers' departure to Los Angeles.
Pros: Stevens is an innovative coach, whose use of statistics is one of his greatest strengths. He understands the game and is willing to develop a young team into a contender.
Cons: The first-year head coach is young (36) and will be in the spotlight throughout this first season in Boston.
Keith Bogans' contract is outrageous.
Keith Bogans and his $5 million contract was a throw-in in the Paul Pierce/Kevin Garnett-to-Brooklyn deal.
Pros: Bogans will be a veteran leader on a young team. His contract is only guaranteed for the first season, followed by two consecutive years of non-guaranteed deals.
Cons: In his 10th season, Bogans finally cashed in, earning $5 million despite averaging just 4.2 points last season.
MarShon Brooks may finally get a serious look in Boston.
MarShon Brooks was another addition to the Pierce/Garnett deal to Brooklyn.
Pros: Brooks gets a second shot at an NBA career after seeing very little time during his tenure with the Nets. Per 36 minutes, according to Basketball-Reference.com, Brooks has averaged over 15 points in each of the past two seasons.
Cons: It's unclear where exactly Brooks will fit. Currently, the Celtics have Avery Bradley, Courtney Lee and Jordan Crawford as other possible shooting guards. Unless Boston utilizes Brooks like it attempted to do with Terrence Williams (using him as a backup point guard), it's hard to see him getting a fair shot at significant minutes.
Danny Ainge has made some brilliant moves this offseason.
Vitor Faverani will be an intriguing option at center for the Celtics this season.
Pros: Faverani, like rookie Kelly Olynyk, is incredibly athletic. He likes to finish around the rim and has a decent shot. His contract, three years for $6 million, is also very cap-friendly.
Cons: The 7-footer isn't known for his defense, and he's another young body that doesn't have much professional experience.
Humphries could be fighting his way out of Boston.
Forward Kris Humphries joins the rebuilding Celtics as purely a trade piece for the future.
Pros: Humphries has a $12 million deal for one year, a decent contract for a big who can still score and rebound at an efficient rate. Boston has widely been rumored to flip Humphries' contract before opening night, according to Comcast SportsNet New England.
Cons: The forward seems disinterested in remaining with Boston. If the Celtics can't flip him, they'll have to bank on Humphries playing at a high level in the last year of his contract before one more big payday.
Olynyk has a chance to be a star in this league.
Kelly Olynyk is an intriguing option as the No. 13 overall pick from the 2013 NBA draft.
Pros: Olynyk is a pretty solid athlete, showing off his ball-handling skills in the summer league, as well as his ability to knock down outside shots and space the floor. He's incredibly athletic and simply has a nose for the ball.
Cons: The 7-footer's lanky frame doesn't bode well for the NBA grind. He's not a great rebounder and is already dealing with plantar fasciitis.
Pressey could be a great option behind Rajon Rondo.
Phil Pressey turned some heads during the Orlando Summer League and now holds a fully guaranteed first year on a three-year contract.
Pros: Pressey showed off his ability to control the tempo of the offense and his ball-handling skills over the summer. If he develops quickly, Pressey could become the permanent backup guard behind All-Star Rajon Rondo.
Cons: The first-year point guard struggled with turnovers despite his strong play in summer league, something the Celtics can't afford in a backup point guard.
Iverson will have time to develop in Turkey.
General manager Danny Ainge bought a second-round pick in order to select Colton Iverson at No. 53.
Pros: Iverson is a physical center who can rebound and play solid post defense.
Cons: As a true center, Iverson is still very much a project big man, leading to his signing of a two-year deal in Turkey.
Wallace and Garnett will switch uniforms this season.
Gerald Wallace was a key member of the deal that brought multiple draft picks to the Celtics, while sending Pierce, Garnett and Jason Terry to Brooklyn.
Pros: Wallace is a veteran leader, who at one point took the Charlotte Bobcats to their only playoff position.
Cons: The 13-year veteran's skill set has deteriorated over the past few seasons, averaging just 7.7 points and 4.6 rebounds last season. He also still has three years and over $30 million left on his contract.
