Former Gonzaga Forward Ben Gregg Inks Deal with Eastern Conference Powerhouse originally appeared on Athlon Sports.
The conclusion of the NBA draft always results in a flurry of undrafted players getting signed by NBA clubs. Some end up on two-way contracts, meaning they’ll split time in the NBA and the G-League, some end up on Exhibit 10 contracts which guarantees them a spot on the team’s G-League roster, and others are simply invited to join the team in Summer League in Las Vegas.
The latter is the case for former Gonzaga forward Ben Gregg, who will join the Boston Celtics in summer league – where he will compete in an attempt to earn a two-way or exhibit 10 contract heading into training camp and the 2025-26 NBA season.
Gregg did not participate in any of the big pre-draft events like the NBA draft combine, G-League elite camp, or Portsmouth Invitational, but he did have quite a few individual workouts with teams.
Boston will get a longer look at the 6’9 forward, who averaged 9 points and 5.3 rebounds the past two seasons at Gonzaga while starting 39 out of 70 games and shooting a ridiculous 73.1% on two pointers and 76% from the free throw line.
Gregg’s professional future largely hinges on his ability to knock down outside shots, a skill that adds tremendous value to his profile as a modern NBA stretch four.
Gregg shot 37.7% from three in 2022-23 and again in 2023-24, but an ugly 6-34 (17.6%) slump resulted in just a 27.1% clip last year for the Zags.
If the big man shoots it well in summer league it could help him snag a valuable exhibit 10 contract which would land him with Boston’s G-League affiliate in Maine.
Gregg joins Ryan Nembhard (Dallas) in inking his first NBA contract this week, while fellow Zag seniors Khalif Battle and Nolan Hickman remain unsigned as of this writing.
