It's unusual to hear a current NFL player criticize the league, let alone talk frankly about its handling of concussions or its response to domestic violence scandals.
But a new book does just that. It's called NFL Confidential, a memoir of the 2014 football season written by a player who goes only by Johnny Anonymous.
The player spoke with All Things Considered host Audie Cornish this week, after NPR confirmed his identity before the interview.
He says he loves playing the game but thinks the NFL is manipulative and exploitative.
