Obviously people who think Brady would leave only read the quote and didnt see his actual expression. He had a half smile on his face, insinuating he wasnt being completely serious. Even by just reading the quote online or in the paper one should easily have been able to deduce that he didnt mean he would literally follow Moss wherever he goes. BUT, he didnt completely toss that out there for humor, there was a point behind behind him saying that, even if it was subtle. When he made that comment threw that comment, even half jokingly, he sorta threw a warning shot saying that, unlike Branch, he wouldn't take Moss leaving lying down.
