These criticisms of Bronco could possibly be spot on, but there is no way to prove it. On the other hand, they could be completely backwards; maybe the firesides are improving performance, but the teams talent sucks so bad that we are still losing games (yes, I realize that is a stupid example, work with me here).
What I am trying to say is: correlation does not equal causation. I find it hard to believe that firesides, "football is 5th", or any other stupid Bronco criticism is having enough impact on the team to cause us to lose games. Sure, they could be a factor... a VERY minor one. There really is no way to know.
