Celtics Projected to Add Playmaking Forward in New 2026 Mock Draft

The Boston Celtics own their own pick for the 2026 NBA Draft. That was part of the reason some sections of the fanbase called on the team to embrace a tanking season this summer, especially with the uncertainty surrounding Jayson Tatum’s return from his Achilles tendon injury.

Boston opted against a tanking season and has been one of the more surprising teams in the Eastern Conference, building an 18-11 record and occupying the third seed in the East. As such, the Celtics likely will pick in the late 20s when the 2026 NBA Draft rolls around next summer.

In a recent mock draft from Bleacher Report’s draft expert Jonathan Wasserman, the Celtics are projected to add another power forward to their roster. Joshua Jefferson is a 6-foot-9 forward who is impressing for Iowa State.

“Joshua Jefferson has registered on scouts’ radar with his improved shooting and playmaking at 6’9″, 240 pounds,” Wasserman wrote. “He’s making spot-up threes with persuasive fluidity. Passing has always been a strength, but more offense is running through him, and it’s shining more light on his playmaking potential. His 24 points against Iowa really stood out, with Jefferson confidently stepping into threes and generating offense off his dribble. His versatility will help cast a wide net of suitors.”

In his article, Wasserman likened Jefferson’s skill set and potential to that of Kyle Anderson. “Slo-Mo” is currently in his 12th NBA season. Jefferson would be considered a success if he could emulate Anderson’s longevity in the league.

Jefferson is currently in his fourth collegiate season. He spent two years at St. Mary’s before transferring to Iowa State. This season, he’s averaging 17.7 points, 5 assists and 7 rebounds per game, shooting 55.3% from the field and 43.3% from deep.

If the Celtics do draft Jefferson, he will face considerable competition to earn minutes on Mazzulla’s team. Boston already has Tatum, Josh Minott, Hugo Gonzalez and Jordan Walsh, who are all capable of playing at the four. Still, if Boston views Jefferson as the best player on the board come draft night, then it makes sense to pick him and figure out the rest later.
