Fans have had a lot of frustrations with Bronco over the last several years. The Riley Nelson 'grittiness' debacle. Utah. The Jake Heaps debacle. Football is fifth. Quest for Perfection. Hiring woeful assistants. His tone-deaf, and sometimes hostile, attitude towards fans. Having a least a couple of games every year where we look woefully unprepared or unmotivated. Seeing rivals in BCS bowls while we're perpetually on the outside. And Utah.
I think that the way the wheels have come off the last few games has just caused a lot of lingering doubts and frustrations to bubble to the surface. Fans are starting to believe that Bronco's brand of head coaching is causing us to slide into mediocrity and irrelevance.
