Bronco has no responsibility to look out for the interests of BYU. I highly doubt he's going out of his way to screw us over.
What he does have is a duty to do what's in the best interest of his current program and conference. If doing that doesn't help BYU it's really not his problem.
BYU decided to be an independent. That decision may prove to have unforeseen negative ramifications. These ramifications are BYU's responsibility and no one else's.
