DJ Irons is tough as nails. Gainesville High’s junior quarterback was eluding defenders in the backfield and scrambling for positive yardage, and kept the chains moving with his even dissemination of the ball with throws to his receivers — all while battling discomfort from a hit from a Habersham Central defender to his right tricep during Friday’s 24-7 Red Elephants victory in Mount Airy. The pain from the hit during the second drive for Gainesville’s offense might have made it hard to get a lot of zip on the ball, according to Irons, but it didn’t have a negative impact on his statistics.
