The last time the Raiders made a quarterback switch in large part because of intangibles, Rich Gannon was as subtle as a drill sergeant and demanded his teammates follow along. Matt Flynn, the presumptive starter in 2013, has spent a lot of time talking football with Gannon -- the former Raiders quarterback was a color analyst for Green Bay Packers preseason games and spent a lot of time at the facility -- but is taking his time in taking over. "Everybody has a different leadership style," Flynn said Monday after a Raiders practice. "If you're going to become a leader, you need to find that niche, how you fit into the system, fit into guys in the locker room, and just go accordingly. "It's something you feel out as you work with the guys and are around them." The Raiders offense with Flynn and a new system devised by offensive coordinator Greg Olson remains a work in progress. A week ago, the Raiders came off Memorial Day weekend with a dreadful practice in terms of the passing game before the assembled media. Things got off to a shaky start again Monday. One of Flynn's first passes bounced off the hands of wide receiver Rod Streater, and his next throw was too high for Denarius Moore. Things got better, however, as the Raiders continued to work on the kind of short, safe throws that keep drives alive before graduating to more intermediate and deep passing. "We're doing a lot of motions and trying to get favorable matchups," Flynn said. "There are always deep options, but right now I think we're trying to get some completions, not force anything downfield and really kind of taking what they're giving us." While Gannon came to the Raiders as primarily a backup, he still had 58 NFL starts. Flynn has just two over his five seasons with the Packers and Seattle Seahawks, so Raiders coach Dennis Allen thinks every offseason practice is crucial.
