Throughout the National Football League there have been many great players that have announced retirement. Some of the announced retirements have been very shocking to the football fanatics. Other retirements many people saw it coming due to the player's age. Peyton Manning was one of those retirements that everyone knew was going to happen. Even though he announced his retirement earlier in the 2015 season, a lot of people knew it was his last season in the NFL. He finished his career as a champion and that was great. He is overthinking if he still wants to retire but at age 39, and almost turning 40, I believe it is time to retire. Another retirement that everyone knew was going to happen was Charles Woodson because of his age. He didn't have anything to prove. He is already one of the best cornerbacks in history. Retirements that were shocking to football fanatics were running back Marshawn Lynch and wide receiver Calvin Johnson. Nobody was expecting any of these two talented players to retire. It was a shock to everyone because Johnson, who has never won a Super Bowl championship, is retiring at an early age, 30. Marshawn Lynch was also a dynamic player that nobody believed was going to retire at an early age in his career, 29. Many people believe that the reason he is retiring is because of the injuries that he suffered in the 2015 season but nobody knows it there is more to his surprise retirement. Another player that retired was Jerod Mayo and he played for the Patriots. He was a Linebacker and the coaching staff was in shock and no one knows the reason for his retirement.
