Only 16 players remain from the San Francisco 49ers' Super Bowl XLVII roster—a number that has dwindled significantly after what has been a wild offseason for the Red and Gold.
With so many departures this offseason—such as running back Frank Gore, linebacker Patrick Willis, defensive end Justin Smith and, most recently, right tackle Anthony Davis—the 49ers will insert a sizable number of new starters into their lineup in 2015.
Some of these roles are unquestionably more important than others. But each new starter will have a critical role in the team's future this season.
