The four-year rebuild that has transformed the Boston Celtics

Updated: August 16, 2017

After the Boston Celtics were bounced from the opening round of the 2013 playoffs, it was painfully obvious it was time for a rebuild.

Even head coach Doc Rivers, the man at the helm of two NBA Finals appearances and one championship over the previous six seasons, started yearning for greener pastures.

By late June that year, the Celtics had agreed to deals that would deliver Rivers to the LA Clippers and aging stars and future Hall of Famers Kevin Garnett and Paul Pierce to the Brooklyn Nets in a jaw-dropping blockbuster.

Summer Forecast, Eastern Conference standings for 2017-18

How will the East standings project in 2017-18? Will there be changes at the top? Our ESPN Forecast panel returns in this year’s Summer Forecast!

  • The Celtics called on their ultimate weapon to bring Gordon Hayward to Boston

    The Celtics pulled out all the stops during their free-agent pitch to Gordon Hayward. But in the end, it came down to master recruiter Brad Stevens and the power of the Butler Bulldogs connection.

  • Next NBA superteam? Nine teams to watch

    Nine NBA franchises have superteam potential to challenge the Warriors’ juggernaut. Here’s how they might get their superstars.

  • Celtics president of basketball operations Danny Ainge then hired 36-year-old college wunderkind Brad Stevens as the team’s new head coach, giving him a six-year deal that underscored the daunting nature of the process that was ahead.

    A mere four years after hitting the reset button, the Celtics are coming off a season in which they won an East-best 53 games and appear on the cusp of returning to legitimate title contention. How did Boston turn things around so quickly?

    Ainge and his front-office staff relentlessly overhauled the Celtics’ roster, targeting undervalued talent that formed Boston’s chip-on-their-shoulder core while also feverishly stockpiling future draft picks. They hit a couple of home runs along the way (Boston is still collecting picks from the Pierce/Garnett swap and got All-NBA guard Isaiah Thomas virtually for free thanks to the aftershocks of the Nets blockbuster).

    Stevens has squeezed every drop of talent out of all the players that have passed through — and there has been many of them — and the rest of the league, including some of the biggest free agents of the past two summers, took notice of Boston’s expedited climb and have rushed to join the voyage.

    The Celtics made more than 70 major moves over the past four years, including 21 trades that helped bring back 16 future draft picks — and plenty of win shares (WS) — to Boston. A look at how the franchise fast forwarded through the rebuilding process:

    There’s a rather hilarious photo from when the Celtics introduced Keith Bogans, MarShon Brooks, and Kris Humphries — the primary player haul from the Nets blockbuster — and only Stevens, two weeks into the job, is smiling. Bogans, who earned an absurd $5 million windfall in order for Boston to maximize a trade exception, and Brooks look like hostages, while Humphries and Ainge seem leery at best.

    Boston won just 25 games that season, but Stevens offered a glimpse into his ability to maximize talent, turning fringe NBA player Jordan Crawford into an Eastern Conference Player of the Week in December. Stevens’ first season featured a mere two in-season trades, but Boston’s roster overhaul was just warming up.

    Here’s all you need to know: With this summer’s trade of Avery Bradley to the Detroit Pistons, not a single player from that 2013-14 season remains on Boston’s current roster.

    It’s easy to forget now, but Celtics fans weren’t initially thrilled with Boston’s decision to trade away Pierce and Garnett. The player haul was underwhelming and the future draft picks received didn’t seem all that glitzy considering Brooklyn was perceived as an immediate title contender after adding Boston’s two stars.

    Unfortunately for the Nets, they almost immediately imploded. While James Young didn’t pan out from the 2014 draft, there are high hopes that the Celtics have two pieces of their future core in Jaylen Brown and Jayson Tatum. The Celtics will also collect the Nets’ 2018 first-round pick, which should be another high lottery selection, to wrap up one of the most lopsided deals in recent NBA history.

    The Nets blockbuster is most often referenced as Ainge’s best move, but the 2014-15 season was a master class in roster reshaping.

    Less than a year after naming Rondo the 15th team captain in Celtics history, Ainge made a surprising December deal that moved the guard to Dallas for a package of picks and players. Crowder emerged as the gem of the swap, blossoming into a two-way force with a bigger role in Boston. Rondo’s time in Dallas couldn’t have gone worse and the Mavericks happily let him walk away after the season.

    Crowder later re-signed with Boston on a team-friendly five-year, $35 million contract that makes him one of the best values in the NBA. Boston’s 2017-18 roster will feature two rookies that were culled from this deal (or its offshoots) in Guerschon Yabusele (16th in 2016) and Semi Ojeleye (37th in 2017).

    In all, Ainge made 11 trades in a seven-month span, including one stretch in January when the Celtics completed four swaps in a week. The Celtics carried a staggering 41 different players during the regular season but emerged from all the wheeling and dealing with Crowder and another building block: Isaiah Thomas.

    Stevens has often noted how, just minutes before the 2015 trade deadline, he didn’t think Boston was making a move. But the Phoenix Suns re-engaged the Celtics on their interest in Thomas, and a deal came together quickly.

    Suns GM Ryan McDonough later admitted he wished he had a mulligan, as the Celtics gave up just Cleveland’s first-round pick — acquired in July 2014 for the Pierce trade exception — and veteran Thornton to land Thomas.

    Since the deal, Thomas has earned two All-Star appearances and finished fifth in MVP voting last season while earning his first All-NBA selection. Even as the Celtics have added impact players such as Gordon Hayward and Al Horford, Thomas remains the face of the franchise at age 28.

    With Stevens craving more roster continuity, Boston’s moves slowed, including a quiet trade deadline in February 2016. The Celtics won 48 games, but a mind-numbing four-way tiebreaker forced them to open the playoffs on the road against the Atlanta Hawks. The fifth-seeded Celtics were eliminated in six games but made enough of an impression on Hawks big man Horford that he signed with the team as a free agent two months later.

    The Celtics went nearly two decades without honest-to-goodness cap space but entered the summer of 2016 with room for two max contracts.

    Ainge swung for the fences, luring Horford away from the Hawks and making Kevin Durant think hard about Boston’s situation before electing to sign with Golden State. The Celtics utilized three first-round picks in June’s draft, turning Brooklyn’s No. 3 pick into Brown then drafting Yabusele (16th) and Zizic (23rd) before stashing them overseas for the year.

    The Celtics again limited their trade activity and were rewarded by more growth from their core. Thomas led the East in scoring and Boston won an East-best 53 games and landed the top seed before bowing to the Cavaliers in the East finals when Thomas was forced out after just six quarters due to a nagging hip injury.


    Other notable transactions

    July 27, 2016: Signed Gerald Green (one year, $1.3 million)
    July 27, 2016: Signed Zeller (two years, $16 million)
    June 19, 2017: Traded 2017 first-round pick (Markelle Fultz) for a 2017 first-round pick (Tatum) and a future first-round pick
    June 22, 2017: Drafted Tatum (third), Ojeleye (37th), Allen (53rd) and Bird (56th)

    Season totals

    Moves: 11 | Trades: 1 | Future picks added: 2

    The Celtics, the East’s No. 1 seed last season, entered the summer armed with the No. 1 pick thanks to a fortuitous option to swap picks with the Nets (the KG/Pierce blockbuster never quite stops giving).

    Boston could have been content to add a prized top pick and run it back with much of the same faces. Instead, Ainge dealt the No. 1 pick to the Philadelphia 76ers for the No. 3 pick and what might be another lottery pick in one of the next two drafts. Boston then drafted Jayson Tatum, who displayed an NBA-ready offensive game in summer league, and signed the best available free agent in Gordon Hayward.

    Signing Hayward to a max deal meant dealing Avery Bradley, the longest tenured player on the team, to the Pistons, and Boston overhauled the entire back end of its roster while bringing back just six players from last year’s team. The Celtics believe they are a better team than last season, though team brass admit they must see how the pieces come together.

    Regardless, Boston is positioned to again challenge for the top spot in the East, particularly if chaos continues to cloud Cleveland.


    Other notable transactions

    July 1, 2017: Signed Zizic (five years, $15.4 million)
    July 2, 2017: Waived Zeller
    July 7, 2017: Traded Bradley and a 2019 second-round pick for Marcus Morris
    July 15, 2017: Signed Nader (four years, $6 million)
    July 19, 2017: Signed Aron Baynes (one year, $4.3 million)
    July 20, 2017: Signed Yabusele (five years, $19.5 million) and Daniel Theis (two years, $2.2 million)
    July 31, 2017: Signed Shane Larkin (one year, $1.5 million)

    The Celtics’ future is particularly bright with a young core helmed by Brooklyn-delivered assets like Brown and Tatum. What’s more, the Celtics could still have as many as six first-round picks over the next two drafts. Those picks will either allow Boston to infuse its roster with low-cost talent or could be used to add even more proven talent via the trade route. After all, the last four years have only cemented Ainge’s “Trader Danny” moniker.
