If there is one thing Bronco can do as a HC is watch his team flame out in a single game or multiple games and then right the ship for the rest of the season. Unfortunately that means that the season is pretty much over when this happens. Either as the result of losing out on a MWC championship or falling out of any hope for a NY6 bowl, etc.
Scenario #2 only happens if Taysom comes back healthy and stays healthy....and we get someone to run the defense.
