Detroit Lions star receiver Calvin Johnson told his family and a close circle of friends before the past season that 2015-16 would be his final season in the NFL. He delivered the same message to coach Jim Caldwell the day after the regular season ended, sources told ESPN.
Caldwell told Johnson not to rush his decision and to take his time, sources told ESPN. Out of respect to Caldwell, Johnson agreed to do just that, according to sources.
The Lions have not given up hope that Johnson will change his mind, but one person who knows Johnson well said, "He's pretty content with his decision."
