The Boston Celtics have brought on a free agent guard mere days prior to the start of the 2025-26 NBA season.

Sources inform Keith Smith of Spotrac that Boston has inked undrafted rookie former St. John's guard Aaron Scott via an Exhibit 10 training camp agreement.

Given his Exhibit 10 contract status, Scott will likely be waived pretty soon, and in that scenario will probably sign an affiliate deal with Boston's NBAGL affiliate, the Maine Celtics.

Bobby Manning of CLNS takes stock of the Maine squad's impending roster. Assuming Scott will join it, the group will be led by two-way rookie signings Amari Williams and Max Shulga, plus returning two-way signing Ron Harper Jr.

Should Scott spend at least 60 days with Maine, he'll be at least eligible to earn a bonus worth as much as $85,300. That may be small potatoes for an NBA player, but even for a G League player that's nothing to sneeze at. General NBAGL salaries are worth just $40,500.

The 6-foot-7 swingman averaged 8.4 points while slashing .389/.293/.810, 4.3 boards, 1.4 swipes, 1.0 dimes and 0.6 rejections per in 36 games last year for St. John's (30 starts). He had logged his first three NCAA seasons at North Texas, and was named to the CUSA All-Freshman Team while there.

If Scott pops in the G League, maybe he'll get another look on Joe Mazzulla's main roster. Boston is looking for young, cost-controlled prospects during what is shaping up to be a major year of change.

A Future NBA 'Sleeper,' Perhaps?

According to CJ Moore of The Athletic, Scott impressed NBA scouts in pre-draft workouts this spring and summer, and although he did go undrafted, he is considered a potential long-term "sleeper" to stick in an NBA roster.

"Aaron Scott will surprise some people in workouts. Not to get drafted, but I could see him playing Summer League and getting an Exhibit 10 or a two-way and making it from there, because he’s a better shooter than his percentage," Moore writes.

That 29.3 percent 3-point rate on 4.2 triple tries a night actually represented a massive dip, as Scott had connected on 40.8 percent of his 1.3 takes as a sophomore and 37.0 percent of his 3.5 tries as a junior.
