Ya tell us all about the arguments Brady had with belicheat and then see how many believe you. Nobody, including me has said anything about a player yelling at players on the sidelines. Heck Irvin was well known to do that but yelling at players is not the same as arguing with coaches on the sidelines. Oh and all these players that you say argue with their coaches on the sidelines and how many found themselves released either before the end of the season or after the season? Like I said, coaches and GM's don't go for players disrespecting coaches on the sidelines. By arguing with them they are disrespecting their authority they have. Also when you grow up and get a job you'll learn that you can't argue with your boss and then expect to keep your job.
