Cal football fans figured they’d seen the last of Demariay Drew when he was charged in connection with a felony assault on a fellow student in May 2014. Suspended from school, he chose the long road back, attending Butte JC while undertaking community service and anger-management classes, as well as scrutiny over his grades and behavior. Back with the team as a non-scholarship junior free safety, Drew has been a glowing presence in the secondary and made the defensive unit’s biggest play against Washington State on Saturdaywhen he intercepted a Luke Falk pass at the 10-yard line with 3:29 left. Dennis Erickson, who didn’t leave much of an impression as the 49ers’ head coach (2003-04) and seemed sadly miscast, is thriving as the Utes’ assistant in charge of running backs, including the renowned Devontae Booker. [...] move the kickoff back 5 yards, so we see more returns. Everyone seems to like Jim Tomsula as a man, but is he an NFL head coach?
