It's fascinating when a NFL player retires in his prime.
It's hard to imagine, for most of us. To play in the NFL, and make a tremendous living, seems like the pinnacle.
It was, in some ways, for Rashard Mendenhall. The former Steelers and Cardinals running back, who decided to retire after six seasons, said in a piece in the Huffington Post explaining his retirement that he loved playing in the NFL and had "tons of fun." It wasn't a physical issue. He just didn't want to do it anymore, so he walked away at age 26.
