Over the past few months, the NFL lineman was involved in a bizarre gym altercation and also dealt with threats from his former Miami Dolphins teammate, Jonathan Martin.

Richie says he's been trying to relax and meditate, and feels he's in a much better place in his life. He also tells TMZ Sports he's praying for Martin, who he still considers to be a friend.

"I wish nothing but well for him."
