It's not up to Husker fans to take other head coaches to task...
But, in general, I think you've got this all backwards. Bo needed to learn to handle the media frenzy better for his sake and the sake of the team. It's never been that the media is in the wrong for not being nice to Bo. The spotlight is intense everywhere you go. Whatever the coach, whatever the media, you'll have guys who for are critical, and oftentimes unfairly so. Having to handle that is part of the deal - it comes with the territory.
If a HC is unable to handle it, to the extent that he ends up creating enemies out of local media members when he could avoid doing so, or setting a standoffish tone for the program vs. the reporters or the fanbase - that is troublesome. Not because it makes Bo such a bad guy. Just trouble for the program.
Thankfully, Bo has gotten much, much better at this over time. Hey, he's a first time HC here. He was hired fairly young. You go through a learning process. I wouldn't agree with personal indictments of Bo's character based on his handling of the media. But I wouldn't disagree with most of the criticism.
In my mind, the best in the business at handling the media is Bill Belichick. Bill is a complete master at saying all the right things, and he doesn't fly off the handle. But you know what? He also says nothing. The CIA leaks more information than the Patriots organization. I've never seen a coach so adept at pouring out a million words while not saying anything. He's a total pro. Of course, the same may not apply to how he interacts with referees, but let's face it, football coaches and zebras are natural enemies. And it's a predator-prey relationship.
