I was at a practice a few years back. O'Brien was there talking to KF when BF unleashes some colorful language on the O-linemen. KF looks at O'Brien and says, "He gets it from his mother", and they both started laughing. There was also some talk years back of BF's language at some event in Chicago. Well, KF couldn't laugh this one off and blame mom. I can understand BF's frustration when everything is there offensively but we find ways to screw plays and drives up, but a 'short burst' would have sufficed to express his displeasure. I think there should be some sort of discipline involved, but he's still a fairly young man and hopefully will learn that he has to keep it together. Offensive coordinators have got to be thinking ahead at all times, not 'losing it' in the moment. Just my opinion.
Ya good points, that kind of emotion, don't mind as much in a DC, actually like it. But OC, not so good.
