Nearly eight years after his stunning retirement, Calvin Johnson says his relationship with the Lions is “trending up.”

Johnson, one of the most talented players in NFL history, spoke to The Post on behalf of Primitiv Performance — a company that he co-owns — that is launching a line of CBD products in Michigan this week.

While he was one of the Lions’ most decorated players in his career, which spanned from 2007-15, there was acrimony after his retirement. The team recouped $1.6 million of his signing bonus, and he has maintained for years a desire for them to pay him him back.

“We’re trending up. We’re trying to come together and make something happen,” Johnson, a 2021 Hall of Fame inductee, said. “Obviously I’d love to be around the team and do more things there and help the guys out. It’s good that we’re moving in the right direction.”
