Since his debut as a defensive coordinator at the collegiate level, Ted Roof has never been afraid to take a risk or dial up pressure more frequently than other coordinators. This has been, in many ways, a big key to his success at the FBS level -- Roof has always had a way of keeping quarterbacks and offensive play-callers off balance and waiting anxiously for the next snap. After getting away from that aggressive philosophy a bit during the 2014 campaign, it now appears that Roof and his staff finally have the personnel to make it work in the 2015 season.
