If the NF mandates a shot clock in the next few years, you can bet virtually every state assn. will ignore the mandate. I don't think there's a school board out there that has shot clocks on it's list of the top 1000 things on which to spend money.
I think the only way schools would install shot clocks would be if a corporate sponsor donates the clocks and pays for the installation. Phil Knight - are you listening?
