On September 20, 2025, the Celtics made a strategic cut, waiving undrafted rookie guard Hayden Gray from his Exhibit 10 contract, per Keith Smith of Spotrac. The 6’3” guard out of UC San Diego, known for his 38.1% three-point shooting and pesky on-ball defense in the Big West Conference, didn’t make the main roster but isn’t done with Boston yet. Gray is set to join the Maine Celtics, Boston’s G League affiliate, on an affiliate deal for the 2025-26 season. This move is more than a demotion—it’s a calculated bet on development with tangible upside.
Exhibit 10 contracts, as Smith notes, come with a sweetener: players cut and sent to the G League can earn bonuses up to $85,300 if they stay rostered for at least 60 days. For Gray, who averaged 12.4 PPG and 3.8 APG in his senior year, this is a chance to showcase his playmaking (1.9 assist-to-turnover ratio) and earn a call-up. His Summer League stint—6.2 PPG off the bench in Las Vegas—showed flashes of a combo guard who could complement Boston’s pace-and-space system (10th in pace last season, 11.8 fastbreak PPG). On X, fans like @CelticsPride18 are optimistic: “Hayden Gray to Maine? Smart move. Kid’s got range and hustle—bet he’s back on a 10-day by January.” Others, however, see it as a long shot, with one user tweeting, “Another G League stash? Celtics need vets, not projects.”
Gray’s path isn’t unique but carries stakes. A strong G League season (think 15+ PPG, 40% from three) could position him for a two-way contract or 10-day deal, especially if injuries hit Boston’s backcourt, already thin with Jrue Holiday’s departure. His defensive tenacity—1.6 steals per game in college—aligns with coach Joe Mazzulla’s emphasis on two-way play, but he’ll need to outshine Maine’s crowded guard rotation to get noticed.
The Roster’s Fringe: Exhibit 10s and Two-Way Battles
Gray’s exit leaves three other Exhibit 10 signings vying for attention as camp looms: swingman Ron Harper Jr., small forward Jalen Bridges, and shooting guard/small forward Kendall Brown. Harper Jr., a 6’6” Rutgers product, brings versatility (11.7 PPG, 5.2 RPG in G League last year) and a knack for cutting. Bridges, out of Baylor, is a 3-and-D prospect with a 41.2% college three-point clip, ideal for Boston’s spacing needs. Brown, a former Pacers two-way player, offers athleticism (7.1 PPG, 58% FG in G League) but needs to refine his jumper (29.4% from three). These three face a steep climb, but their low-cost deals give Boston flexibility to test them in camp.
Meanwhile, Boston’s three two-way slots are occupied by 2025 draft picks: shooting guard Max Shulga (Utah State, 39.8% 3PT), wing RJ Luis Jr. (St. John’s, 6’7” slasher), and center Amari Williams (Drexel, 9.8 RPG, 2.1 BPG). These rookies are locked in for now, but the real intrigue lies with two players on partially guaranteed standard contracts: small forward Jordan Walsh and center Neemias Queta. Walsh, a 2023 second-rounder, has shown defensive promise (1.2 SPG in Summer League) but shot just 31.9% from the field last season. Queta, a 7’0” rim protector, averaged 5.1 PPG and 4.3 RPG in limited NBA minutes, with a 64.4% true shooting percentage that screams efficiency.
The math is tantalizing: if either Walsh or Queta is cut to save cap space (combined $4.8M non-guaranteed), a two-way player like Shulga could slide into the 15-man roster, opening a two-way slot for an Exhibit 10 standout like Bridges. While rare, the precedent exists—think Payton Pritchard’s rise from a late first-rounder to rotation staple. On X, @GreenRunsDeep speculates: “Queta’s got the edge for backup center, but Walsh might be expendable if Harper or Bridges ball out in camp.” The G League could be a proving ground for all, with Maine’s season tipping November 8.
Center Stage: Queta, Boucher, and Garza’s Battle
Queta’s partially guaranteed deal puts him in pole position to compete for the starting center role, especially with Al Horford’s departure and Kristaps Porzingis traded to Charlotte. At 26, Queta’s athleticism (1.9 BPG in G League) and rebounding make him a fit for Mazzulla’s switch-heavy schemes. But he’s not alone—free-agent signings Chris Boucher and Luka Garza are in the mix. Boucher, a 6’9” forward/center, brings elite athleticism (1.4 BPG last year) and could even start at power forward, offering lineup versatility. Garza, a 6’10” big, is a scoring machine (14.8 PPG, 56.7% FG in limited NBA time) but lags defensively.
Advanced metrics favor Queta: his +3.2 net rating in 28 games last season outshines Garza’s -1.1, while Boucher’s 39.1% three-point shooting adds spacing Horford once provided. Training camp will be a proving ground, with Mazzulla likely prioritizing rim protection (Boston ranked 4th in blocks last year, 6.3 BPG). X debates rage, with @CelticsCentral arguing, “Queta’s the future—Garza’s a bucket but can’t guard. Boucher’s too skinny for starting 5.” If Queta secures his guarantee, he could anchor the second unit, freeing Boucher for small-ball lineups.
Tatum’s Shadow: A Gap Year with Opportunity
Jayson Tatum’s absence looms large, with reports from 98.5 The Sports Hub confirming he’s been rehabbing his Achilles at the Auerbach Center “almost every day for months.” His March 2026 return projection leaves Boston leaning on Jaylen Brown (projected 28 PPG) and a retooled supporting cast, including Anfernee Simons and Derrick White. This “gap year” opens minutes for young players like Walsh, who could earn a rotation spot if he improves his shot (career 33.3% 3PT). The Exhibit 10 trio—Harper, Bridges, Brown—face a golden opportunity to impress in camp, especially with Tatum’s 30.1 PPG void exposing Boston’s scoring depth (17th in offensive rating last year, 112.9).
The roster’s youth movement, with rookies and G Leaguers, aligns with GM Brad Stevens’ long-term vision. Cutting Gray saves $1.2M in cap space, keeping Boston under the $208.4M second apron while fostering development in Maine. If Harper or Bridges pops (say, 40% from three in camp), they could follow the path of past G League call-ups like Sam Hauser. The risk? A thin roster could struggle early against a brutal opening schedule (four playoff teams in the first five games).
A Season of Development and Dreams
The Celtics’ decision to waive Hayden Gray is a microcosm of their 2025-26 strategy: develop talent, stay flexible, and build for the future while chasing a play-in spot. Gray’s G League stint could yield dividends, while the Exhibit 10 and two-way battles signal Boston’s faith in youth to bridge the Tatum gap. Queta’s rise, Walsh’s potential, and the center competition will shape the rotation, but the real test comes October 22 against Philly. Can this retooled squad surprise the East, or will the G League grind define their season? Celtics fans, what’s your take—will Gray or an Exhibit 10 steal a roster spot?
