Curtis Riley
When Curtis Riley was on the field this season, Raiders fans across the world knew what was going to happen. Riley was awful at playing his coverages, giving up deep touchdowns nearly every time he was on the field.
Riley did not record a single interception this season, despite getting playing time in most games. If a player is a clear liability, he should be let go, and I believe not bringing back Curtis Riley is an obvious choice.
Not only was Riley bad at coverage and tackling, but he also destroyed his own teammate in Week 16, colliding with Trayvon Mullen in a scary helmet to helmet collision because of his poor tackling form. If the Raiders bring back Curtis Riley, Raider Nation will be the angriest group of people on earth.
