Every head coach has media stipulations written into their contract. I don't know why he did the radio show this time rather than the presser, probably something to do with logistics. I would assume the powers that be that sign his paycheck tell him where to be and when to be there and he says, "ok." It's not like he was dodging anything though. He still addressed that mess of a game on the radio, just like he would've during a press conference.
