Dennison doesn’t bring an overwhelming amount of experience to the table and is better at dealing with running game all of which could lead the Broncos to pair him with a more experienced coach and play caller that has had success with quarterbacks. Josh McDaniels anyone? Just kidding, I thought that was funny.
If you look at the teams that have had success while undergoing a leadership change, they usually have a strong coaching staff that has helped bring balance to an otherwise unstable environment. The Kansas City Chiefs are a good example of this. Where would the Chiefs have been if they had not chosen to bring in Charlie Weis and Romeo Crennel? Probably not in the playoffs. There are a lot of coaches who excel as coordinators and fail as head coaches so finding someone that will give the Broncos an identity will go a long way in determining their success. If John Elway and company elect to go with Dennison, the teams success will have a lot more to do with who fills the coordinator positions than the head coach.
