NAPA, Calif. -- One of the biggest -- if not the biggest -- stories in the Oakland Raiders offensive line room this training camp is about a third-string center.
Before making every single snap for the Raiders in their exhibition opener at the Arizona Cardinals, Ian Silberman had never played center in a competitive game in his football-playing life.
Silberman, a sixth-round draft pick of the San Francisco 49ers in 2015, was converted to the position from guard by Raiders offensive line coach Mike Tice after backup center Jon Feliciano went down with a knee injury in OTAs.
