Disclaimer: The GCCOA is not taking a position of the shot clock. The video and the adoption image is educating our basketball members of the shot clock conversation gaining momentum in Michigan.
Executive Director Dan Young of BCAM – Basketball Coaches Association of Michigan speaks about the shot clock coming to Michigan. He says 75% of their members want the shot clock. They will be submitting a proposal to the MHSAA. Listen to his reasoning and next steps.
