Demias Jimerson of Malvern, Ark., is 11 years old — and he’s so good at football that “he’s going to score almost every time he touches the ball,” according to his intermediate school principal, Terri Bryant. In other words, he’s so good he must be stopped. Because Jimerson runs circles around the other kids on the field, Bryant has decided he’s not allowed to score more than three touchdowns, provided his team has at least a 14-point lead.
