Schopp is a guy, who doesn't like sports other than baseball and tennis. However due to his job, he is required to talk about Football. So... like anyone who doesn't like something, he does his best to relate to it without trying hard and diving into it. What he can do is tell you his thoughts on tickets, jersey colors, stadium concessions, the schedule. and he can formulate opinions on star players. It's also why he can't answer questions about the full roster, scheme, or really analyze anything. He does the bare minimum on topics he has no interest in.
On a side note, it's hilarious to listen to Schopp stammer through his live reader for an RV dealership. He is really trying to make it sound interesting, but it's obvious he can't relate and the only camping he has ever done was at a Hampton Inn. He stops just short of saying "you people" when talking about RV enthusiasts.
