The Detroit Lions offense has changed without Megatron but one thing that hasn't is his decision to leave the NFL.

In a recent interview with Michael Rothstein, Calvin Johnson made it clear that is content with his post-NFL life by simply saying "I'm not coming back, man".

Johnson attributed injuries and not always being competitive as reasons he left the game still in his prime. During his interview with Rothstein he talked about his passion for watching football and the condition of his body.

“I got chronic stuff that everybody has when they’re done playing football for any length of time,” Johnson said. “So the good thing is I’m able to walk. I feel good. I’m able to spend more time with the fam. I’m able to chill.”

"I've been looking forward to sitting back and watching football ever since I stepped into the league. You lose that," Johnson said. "When I was in college, I used to love to watch football on Sundays. And for nine (years), almost a decade I was away from that.

Johnson holds almost all of the receiving records in franchise history and the NFL record for the most receiving yards in a season with 1964 yards. He finished his career with 731 receptions, 11,619, receiving yards and 83 reception touchdowns.

Calvin Johnson was the most feared wide receiver during his nine year NFL career with the Detroit Lions and put the sports world on halt when he announced his retirement at the age of 30.
