It's very hard to talk objectively about something you have a deep emotional interest in. Herbstreit and Desmond Howard played for two of the three biggest-name programs in America (the other being Notre Dame) and handle the difficult situation on total opposite ends of the spectrum.
Desmond Howard picks Michigan to win no matter what and Kirk won't pick Ohio State in a game that's meant to be close at all
I don't think either of them is "right" to approach it that way, but following football my whole life it's very hard to be objective about it, and if you try to be objective at all costs, you'll probably end up going back around in circles and showing bias against your preferred team like Herbie does
