Before most high school football teams in the state hit the gridiron for their first regular season game, the Johnson High football team will have already been tested. The Knights, under first-year head coach Jason Roquemore, are kicking off the 2012 season on Aug. 24 at home against West Hall in the annual Battle of Oakwood. That means that Roquemore, hired in June after the departure of previous coach Paul Friel, has had to do a lot of work in a hurry to evaluate the team and install new systems.
