The big thing you guys are missing here is what ainge said to somebody on Twitter after the interview. He didn’t request Heupel to come on to the radio show, but Heupel asked him if he could. That is huge IMO because it shows that our coach cares and wants to tell everyone how much he loves Tennessee. It’d be different if ainge called and asked him to come on, but Heupel himself requested to.
It doesn't. It doesn't show that. That's projection. Nothing in that call was atypical of any coach who's doing the "I love it here, my family loves it here" speech for the fans.
What that call shows is that Heupel wanted to message to the fanbase that everything was fine, because a happy fanbase is easier to recruit with than a disgruntled fanbase. Now why do you think he did that? Because of "how much he loves Tennessee"? Come on, you have to think about this. That's not practical. What's a practical reason? It's recruiting.
Let's look at this from a practical standpoint. If Heupel is rumored to be looking at OU, then it could hurt Tennessee's recruiting during a critical signing period - and that recruiting is already trying to get past those NCAA sanction rumors they're stuck with. Both Heupel and Tennessee need those rumors squashed because right now his job is being the head coach at Tennessee. If he's not under consideration at OU, then he especially needs those rumors squashed.
Basically, OU's job came open, the collective Tennessee fan base began to hyperventilate, and Danny White (and other people in the UTAD) probably started getting a lot of upfront and backchannel inquiries asking about the risk of losing Heupel. So they arranged the appearance to help settle people down. They know how skittish Tennessee fans are. It's not in either of their best interests for Tennessee fans to pulling fire alarms about OU - even if OU might be considering Heupel for the job.
And look, maybe Heupel does like it here. Maybe he even does love it here, as he said. That does NOT mean they're somehow "in love" with Tennessee and never want to leave. Anyone who hears that is not listening to what Heupel actually said. Coaching is a business. You can love any place if the number is right.
