I don't know what the "certain GPA" is, but since Mike was Academic All-ACC, I'm sure he meets the minimum and Duke won't be adversely affected.
That's a lot larger number than I expected. Almost half in baseball. 74 adjustments for men's basketball, which also sounds like a lot given there are only 60 total picks in the NBA draft - I guess people go professionally elsewhere as well.694 student-athletes were granted APR adjustments for professional departures
