I personally think it's awesome. It really does suck to be a Chiefs fan right now - there's no use in sugar coating it. The fact that Pioli hasn't done ANYTHING to even TRY to address the QB situation in KC is criminal.
Will the banner make any difference? Probably not. But it'll at least increase the volume of criticism that the Chiefs have to deal with a bit, and hopefully it'll make Clark realize that people are nearing the end of their tolerance for this experiment.
