Free agent WR Chad Johnson admitted on ESPN's First Take Wednesday that his August arrest for domestic battery, in addition to an obsession with self-promotion, cost him the end of his NFL career. "I messed up. I messed up," said Johnson. "Period. I lost everything. Football, my wife, the family I had, over something that didn't really mean anything." Johnson finalized his divorce from Evelyn Lozada in September. "I lost that edge when my focus went away from the game of football," Johnson also conceded. "I know that. I understand that." Johnson says he's now "humbled", and guaranteed that he's "going to play again." He turns 35 in a month.
