Malcolm Montgomery always wants to practice what he preaches. It is the biggest reason why he is no longer the coach of the Warren County High School boys basketball team.Montgomery resigned Thursday, leaving the program after a four-year tenure as the Pioneer head coach. The decision to step down was a tough one for Montgomery, but one he made as he realized he couldn’t make a full investment to the program.“As a coach, I’ve always asked my players to be fully invested in what we’re doing,” said Montgomery.
