The Celtics on Wednesday selected Creighton guard Baylor Scheierman with the 30th and final pick in Round 1 of the 2024 NBA Draft.

It was Boston’s first first-round pick since Brad Stevens took over as president of basketball operations in 2021.

Known for his 3-point shooting prowess, the 6-foot-6, 202-pound Scheierman averaged 18.5 points and 9.0 rebounds for the Bluejays last season. He shot 46.1% from the field and 39.0% from three over his five-year college career, which began at South Dakota State.

ESPN draft analyst Jonathan Givony called Scheierman “a dynamic perimeter scorer who shoots the ball at a high level on the move while contributing with his versatility and feel for the game on the wing.” Scouting reports knock him for his lack of elite athleticism and for his age, as he turns 24 in September.

With most of their title-winning roster locked up for the 2024-25 season, the Celtics entered the draft looking for developmental depth, not immediate contributors. Stevens said in his pre-draft news conference that the team was open to keeping or trading No. 30. MassLive reported Wednesday that Boston was actively shopping the pick.

“If the right person is available at 30, then we will take them,” Stevens said Tuesday. “And if have a couple of people that we think are still the right person, then we’ll see what our options are and what kind of flexibility we have.

“But I anticipate picking a couple (players), whether they are on roster or two-way (contracts), and investing in young players. But I just — if they come in and crack our rotation, then they’re really good, and that’ll be a good thing, too.”

There would have been a financial benefit to trading back for the Celtics.

First-round picks are subject to the NBA’s rookie wage scale, which guarantees each player’s salary for their first two seasons within a predetermined range (with team options in Years 3 and 4). The rookie-year range for the player drafted 30th is between $1.67 million and $2.5 million, which, again, is guaranteed.

There’s no such framework for the second round, where draftees can be signed to rookie minimum or two-way contracts with no guaranteed money required.

For a team with as many highly paid stars as the Celtics — who could hand out additional extensions to Jayson Tatum and Derrick White in the coming weeks — that difference is potentially significant from a salary cap perspective. Especially when, as Stevens put it, the odds of finding a quality player at the end of the first round are “pretty low, generally speaking.”

But the Celtics chose not to pass on Scheierman, who was the 27th-ranked prospect in ESPN’s draft rankings. Stevens said Tuesday that any player Boston picked would have a difficult path to playing time.

“We’ve got a lot of guys back,” Stevens said. “It will be hard for any draft pick to crack our rotation when healthy. So we’ll think about how we can best continue to invest in young players and their development and growth, with the reality that, if we’re able to continue to move forward with this group, these guys are going to be on the court.”

French forward Zaccharie Risacher was the first player selected Wednesday night, going No. 1 overall to the Atlanta Hawks. Three New England collegiate products were lottery picks, including two members of the national champion UConn Huskies: guard Stephon Castle (No. 4, San Antonio) and center Donovan Clingan (No. 7, Portland).

The Clingan pick could have implications for former Celtics big man Robert Williams III, whom Boston traded to the Trail Blazers last summer as part of the return for Jrue Holiday. The Blazers shipped out another piece from that deal Wednesday, reportedly sending ex-Celtics Sixth Man of the Year Malcolm Brogdon and the 14th pick to Washington for forward Deni Avdija.

Providence guard Devin Carter went 13th overall to Sacramento to round out the local lottery selections.

The draft is set to resume at 4 p.m. ET on Thursday. The Celtics own pick No. 54, which they acquired in the draft-night trade that yielded last year’s second-round selection, Jordan Walsh.

Boston traded its own 2024 second (No. 58) in the 2020 deal that sent Gordon Hayward to Charlotte.
