What can the fans do?

In 2007 when Mich was rumored to want Miles, the fans had a march to keep him there. (I never understood that. I didn't care for him then, either.) What is the scene like their in B.R.? Is there any way that Alleva knows how the fans feel? Does he know that this rabid fan base is not satisfied with a team that is in contention every year, but one that actually brings home the trophy? I ask because I don't know if the radio stations are filled with callers who are really mad about the game, or if all of the anger is confined to this board.
