What's returning
Nearly the entire core that led the Celtics to a 20-11 record after the All-Star break, second-best in the Eastern Conference. That slightly overstates how well Boston played; the Celtics' plus-2.9 differential after the break was fourth in the East, and typical of a 48-win team over a full season. Still, Boston's surge into the playoffs was unexpected after trading what were nominally the team's two best players in
Rajon Rondo and
Jeff Green.
Adding point guard
Isaiah Thomas at the trade deadline dramatically changed Boston's offensive ceiling. Thomas was a perfect fit for the Celtics, who desperately needed a shot creator. Thomas used 32.1 percent of Boston's plays after the trade, a rate that would have ranked seventh in the league. But his efficiency actually went up slightly to a career-best .579 true shooting percentage (TS%), and Thomas also handed out 7.4 assists per 36 minutes. The Celtics' offensive rating improved by 10.4 points per 100 possessions with Thomas on the floor, per NBA.com/Stats data, to what would have been the league's third-best mark (109.2).
With Thomas as super-sixth man, shot creation in the starting lineup was turned over to
Evan Turner, who excelled at times in the role. Turner still relies too heavily on pull-up jumpers to be an efficient scorer -- his TS% was a woeful .482 -- but he can make plays for teammates and is a versatile contributor.
Turner's presence as a point forward turned guards
Avery Bradley and
Marcus Smart loose to focus on playing off the ball and defending tenaciously. Bradley was the leading scorer among players who spent the whole season in Boston, though he also shoots too many 2-point jumpers. Smart proved more competent from 3-point range than expected (33.5 percent), but he didn't get to the basket as frequently as hoped. Smart's real value is at the defensive end, where he provides a bulldog presence to complement Bradley's more graceful style.
Upfront, the Celtics have three parts of a solid frontcourt rotation in youngsters
Kelly Olynyk,
Jared Sullinger and
Tyler Zeller. Olynyk's floor spacing, Sullinger's offensive rebounding and Zeller's high-percentage finishing make them valuable pieces. Alas, all three share a common weakness: rim protection.
Perhaps Boston's strongest returning piece is head coach Brad Stevens, who molded this group of misfit toys into a cohesive unit. Using pace and small lineups, Stevens manufactured floor spacing without a single starter who shot appreciably better than league average from 3-point range. He also built a credible defense without the interior presence that is typically required for such performance. Two seasons into his NBA career, Stevens looks like a future star on the sidelines.
Free agents
As part of the return for Rondo,
Jae Crowder was a bargain for the Celtics at the league minimum. He's due for a big raise as a restricted free agent, though he's unlikely to leave. Crowder's energy and strength allowed him to play as an undersized power forward, which hid his poor outside shooting.
Jonas Jerebko also served as a stretch four for Boston after a deadline deal, revitalizing a career that had stagnated in Detroit. Jerebko shot 40.6 percent from 3-point range with the Celtics and averaged 14.1 points and 9.6 rebounds per 36 minutes.
Nobody came calling for veteran
Brandon Bass at the trade deadline, and he ended up starting for Boston in the playoffs. Bass' ability to knock down the midrange jumper and defensive versatility make him an ideal reserve on a good team, a role he'll probably fill elsewhere next season.
Biggest need: Rim protection
As noted, none of the Celtics' big men have a shot-blocking presence. Boston ranked last in the league with 3.6 blocks per game, and opponents made 53.9 percent of their shots within five feet against the Celtics,
the league's third-worst mark, per NBA.com/Stats. Adding even a shot blocker with limitations elsewhere would give Stevens far more options with his frontcourt.
Biggest question: How can the Celtics land a star?
The Celtics have a number of complementary pieces, and possibly even one star -- albeit an unorthodox one -- in Thomas. However, their series against Cleveland reinforced how difficult it will be for Boston to compete with the best teams in the East without adding top-tier talent. The Celtics have the cap space to offer a max deal this summer while bringing everyone else back. Alas, Boston hasn't signed a marquee free agent since landing 34-year-old
Dominique Wilkins in 1994. Celtics insiders will point out the team hasn't tried to do so in years, but the causation runs both directions.
Assuming Boston can't land a star in free agency, the team's best chance of doing so might be with unprotected
Brooklyn Nets picks coming in 2016 and 2018. The Celtics have amassed an impressive war chest of first-round picks, including two this season (along with the third pick of the second round) and likely three next season, so more young talent is on the way.
Ideal offseason
Citing the desire to play a leading role in the weaker Eastern Conference, unrestricted free agent
DeAndre Jordan unexpectedly spurns offers from the
Los Angeles Clippers and other teams to sign with the Celtics. Jordan proves to be the missing piece and helps Boston emerge as the leading threat to the
Cleveland Cavaliers in the East. After their physical playoff series, a rivalry grows between the two teams.
