With all of these various theories and possible explanations going on, Occam’s Razor comes to mind.
“Occam's razor is a principle often attributed to 14th–century friar William of Ockham that says that if you have two competing ideas to explain the same phenomenon, you should prefer the simpler one.”
In my mind, the simpler explanation being that Mullen was in town, players are following him, and jokes are being made on air. They are just waiting to finalize the employment contract and for yesterday’s game to have finished.
Edit: just looked it up - the razor refers to shaving away other explanations. Learned something today!
