In March 2025, he received Tennessee’s Torchbearer Award, the university’s highest honor for students.
Memphis Grizzlies Era (2025–Present)
Despite not being projected as a high-volume scorer, Mashack was highly regarded for his defensive capabilities entering the 2025 NBA Draft.

On February 7, 2026, he recorded his first career start against the Portland Trail Blazers, scoring eight points with a career-high six steals while playing the center position due to roster absences caused by injuries and the trade of Jaren Jackson Jr.
Two days later, Mashack scored a career-high 17 points against the Golden State Warriors.
