This season has been a rough one for the "Bronco is a Mediocre/Bad Coach" crowd.
They have never respected him as a coach and they're still mad Holmoe didn't agree with their assessment of his abilities and fire him years ago, or at least refuse to renew his contract.
Now for them to be proven right about Bronco Virginia must remain a dumpster fire, while BYU must become even better than when Bronco was here. So far the opposite has happened: Virginia has clearly improved under Bronco, while BYU appears to have regressed under Kalani.
As a result, they can't let it go because admitting reality would be admitting they were wrong. Hence the obsession.
