I would guess that nearly 100% of Cougar fans are supportive of Bronco as our HC. I know that all of us on this forum are very happy with not only the success of the program but, more importantly, the direction of the program.
But everything that Bronco has established is still in its infancy. If he were to leave, for any reason, within the next 2 or 3 years I believe it would devestate BYU football. The reason is that there are no potential succesors that can do what Bronco is doing. Even someone from the current coaching would be a cheap imitation of Bronco at this point. I believe the successor to Bronco will need to be someone who has played under him at BYU. But there won't be anyone ready for at least 10 years (but by that time we should have a great pool of former players to choose from). If Bronco can continue to make the program better each year he will have built a real "program" in ten years that will have his fingerprints all over it. And at this point my leading candidate to take over for Bronco is...
Cameron Jensen!
I don't expect Bronco to stay as long as LaVell, but here's hoping for at least 10 more years.
