2018-2019 team autographed basketballs are still available.
Personally I’ve run out of room and am prioritizing final four years and teams with special players like ‘14. Love me some Embiid.
A school sanctioned autograph ball they do every year since the late 90s. I suppose they profit around $75-100 per ball x1-2k. The balls likely pay for a scholarship or two.
