While the NFL playoffs continue on without the Cleveland Browns, the NFL offseason is still just under a couple of months away. NFL free agency, the NFL draft and, potentially, a few trades will shake up rosters from top to bottom starting in the middle of March.
The exception to that rule are for players that were either free agents when the regular season ended or were on practice squads. Free agents, like TE Zach Ertz, can sign with whatever team they want. Ertz just joined the Detroit Lions push for the Super Bowl.
