Their job description pretty much entails reading scripts and toeing the company line. The ones you see every year like Tasker are good at doing what they're told. That's why they never call out refs for making bad calls, they only make "tough calls", they never admit when they were wrong, and many times ignore what's going on on the field in favor of human interest stories.
My recommendation is to watch games on mute. I guarantee you that post-game opinions differ between those that watched with the sound on and those that watched it with the sound off.
