One of the tougher jobs in the league in terms of continuity is that of special teams coordinator. The level of turnover from one season to the next is considerable. So, to be in the situation the Raiders are in this season is rare.
Seven players on the roster played the majority of snaps on special teams last season and all of them are back this year. Those players are Marquel Lee, Erik Harris, Derek Carrier, Kyle Wilber, Keith Smith, Nicholas Morrow, and Dwayne Harris.
