It's no secret at this point that Antonio Brown and Ben Roethlisberger aren't the best of friends. While appearing on HBO's The Shop, Brown explained his beef with Roethlisberger, particularly Big Ben's attitude which AB says came across as if he were the team owner. While everyone else laughed at AB's rant on Roethlisberger, it's not hard to tell that Brown has a serious problem with the Steelers quarterback, making his departure from Pittsburgh all the more understandable.
