Many of us grew up in a time when we considered these TV guys to be experts. Well, I don't know if they ever were, but they are simply not that today. They are "sports enthusiasts/entertainers".
If Tom Hanks said he thought the Hawks weren't any good, would anyone care? That's all these guys are - they like talking about sports and they have completely biased opinions. They are no different than that the guy sitting next to you on the bus, except that can tell stories better - maybe.
They are entertainers and nothing else. They have no influence on anything.
