I think you have me confused with someone else regarding Heaps.
Here are some other stats for you to consider (and yes, I know you didn't necessarily want to compare Bronco to any other coach but it does give some meaning to the stats).
For the last 4 yrs, here are the coaching records for Bronco and whitless vs Sagarin's final top 10 and top 30 teams.
Coach / W-L against top 10 / W-L against top 30
Bronco / 0-3 / 4-10
kwhitt / 0-3 / 0-13
