Let him walk: Rashaan Melvin
Rashaan Melvin was brought in to be the other starting cornerback alongside Gareon Conley this season, and he really struggled to make an impact early on. In fact, it was not until late in the season that he finally started to show the kind of promise that the Raiders saw when they signed him to a one-year deal this past offseason.
While Melvin finished strong, he should not be brought back next season, as the Raiders will look to make an investment in their young talent at cornerback. Daryl Worley and Nick Nelson are both very young, and will get a chance to prove their worth this summer, and see who will be the other starter alongside Conley.
In addition, the Raiders could decide to roll with the a cornerback with one of their three first round picks in April, making Melvin expendable. Melvin is going to want a long-term deal with big money likely as he heads into free agency, and at this juncture, the Raiders organization should not commit to him.
