Not that anyone here listens, but in case there is someone.
What you "see" when you "see" Brown "struggle" (enough quotes for you yet) in preseason games, is a guy who has about ONE TENTH the practice reps of the other 3.
They will be keeping Brown or not based on what the coaches see of him in camps and practices, not based on a few preseason plays.
Put another way, we have had a three way QB competition going on, which has limited the reps for Trent, Fitz, and Brohm in practice (because they have to be divided up more among the three). Levi comes last in that parade and gets far fewer than anyone. All of you know this.
But if it entered your thinking at all about what you think you see in a the preseason games, and what Brown has "shown you", none of you mentioned it.
