One of the few constants in the NFL is change.
Head Coach Jack Del Rio said himself during his season-ending press conference that on average, 25 percent of the roster turns over from year to year; such is the business of professional football.
As the Raiders inch through the offseason and prepare for the new league year to begin, the Silver and Black have 13 players scheduled to become unrestricted free agents, and one set to become a restricted free agent.
Free agency officially kicks off this Thursday, March 9 at 1 p.m. PT, but as of today at 9 a.m. PT, impending unrestricted free agents can begin negotiating with any team they choose.
Let's take a look at each of those players that are scheduled to hit free agency for the Silver and Black.
