NFL AM just had a segment on the steelers where they actually said Ben was not happy with the direction the team is headed and will/may ask for a trade this off season. They said some major changes could be in place for the coaching staff. They also alluded to Ben going to Arizona. When asked if Ben would be traded, the organization said. 'NO, unless we can replace him with another franchiser QB'.
Of course this is all speculation, but it must have enough teeth for it finally to be discussed on an nfl program.
