I lumped all 6+ win teams into one boat. If I separated the data (which I didn't think of doing until now) it would give a more fair representation of Bronco's accomplishment or lack thereof.
All of Bronco's bowl opponents won at least 6 games, but no more than 9 games. If we filter that way.
Bronco is 26-12 vs. all opponents*
6-10 vs. majors.
20-2 vs. everybody else.
*Edited. Original Post had data for 8 win teams
