Calvin Johnson and Marshawn Lynch left college together a decade ago and went 10 picks apart in the first round of the 2007 NFL draft.

They worked out together as they prepared for the NFL combine, and they walked away from the game together months apart after the 2015 season.

But while Lynch reconsidered his retirement and eventually returned to football earlier this spring, Johnson, the Detroit Lions' all-time leading receive

"I don’t really think about it too much because I got so much going on," Johnson told the Free Press after his annual "Catching Dreams" football camp Saturday at Southfield High. "I came in with Marshawn. We worked out together down in Orlando with Tom Shaw. I'm going to see him next week because I’m going out there to work with Oakland. But I don’t feel any kind of mixed emotions about it now.

"It doesn't make me think about coming back, not at all."

Johnson, 31, is content in retirement even as he says he doesn't want to "talk Lions too much just because the way our relationship ended."

He's happily married and planning a move to his native Georgia later this year. He's less than a month away from getting his real estate license in Michigan. He still wants to finish his degree at Georgia Tech (and is hoping they offer more online classes to allow him to do so).
