Antonio Brown has been unhappy with the Pittsburgh Steelers for what seems like a while now. At the end of the season, Brown had a dispute with quarterback Ben Roethlisberger which led to the star wide receiver missing the final game of the season. When the Steelers missed the playoffs, Brown trolled the team from social media saying alluding to the fact that he wanted out of town and potentially even wanted to play for the San Francisco 49ers. An interesting proposition that doesn't seem so far off from reality any more thanks to Brown's latest Twitter post that all but confirms Brown is leaving Steel City.
