Sounds reasonable. Perhaps an overwrap for the game with a self adhesive elasticated bandage. Smith and Nephew have a few as to Biersdorf. I have used these with great effect for small muscle strains in the quads and calf. But remember all you are really achieving is an early warning device. It will not prevent hyperextension if he falls on an outstretched hand. Tell him to stay wide and shoot only for three pointers!!
