Athlete Institute, a prep school in Canada, has retired the jerseys of Thon Maker and Jamal Murray.
According to Tipofthetower.com:
In Canadian hoops, few have achieved what Thon Maker and Jamal Murray have accomplished so far in their young careers. Tuesday night was yet another milestone for both players as they had their numbers raised to the rafters at Athlete Institute.
It’s not often a high school program, even a preparatory one, can be able to retire a jersey number. It is even rarer that you can hang up two numbers from the same team and years.
