Joe might be one of the softer skinned personalities at the station. He doesn't take it well when anyone pushes back on him. He spent most of the summer getting preemptively upset when he'd share a non-sports take, then go "what, I only have to talk about sports??? Screw that!"...when nobody took exception to him doing so in the first place. I think at a basic level he considers his opinions "facts" for some reason, then gets mad when anyone disagrees. I like him a lot when he's having fun, but he can also be completely insufferable at times because he comes across as 'Charlie in the mailroom' with some of his takes & associated stubbornness.
His Te'o take was another example of getting caught in a take. He said the NCAA should retire Te'o's number, but rather than catch himself and realize how absurd that was, he got pissy and tripled-down on it. Anyone in their roles is bound to say some stupid shit, so I don't mind the initial opinion, but you should be willing to walk it back or do it with a wink to the audience once you realize how dumb the opinion was.
