Peter King Caught On Hot Mic: "He's Just Fucking Nutty"

During a live look-in during this morning's Dan Patrick Show, guest Peter King dropped an F-bomb. We are, frankly, shocked. We had no idea Peter even knew that sort of language.

Thankfully, Peter quickly took to Twitter to apologize.

More importantly, who were they talking about? Some coach, seemingly, but it's impossible to tell from this clip. Can anyone who was watching or listening to the show put it in context?
