I'll contribute further irritating warnings about doing this plus one positive thing:
1). as LA said, the second most important thing is having a good technological system to broadcast the BS;
2). THE MOST important thing, though, is having a willing ADMINISTRATOR. This is the guy who rounds up all the lazy guys who are just going to "show up", gets the cat herd organized, ties up the practical loose ends, and allows something to happen more than once.
Now the positive thing: On such deals you don't really need to plan much about what you're going to say. General topic areas yes, details and strong agenda no. Whether anyone of you believes it or not [and I suspect that deep down ALL of you do], you know more about what's actually going on with Notre Dame football than any group that is not on the inside. IE studies and discusses ND football more in depth and more intelligently than anywhere.
The bottomline there is that people would tune in to listen because they'll hear things from you that they would not get elsewhere, and with saner comments about it. There have been oldtime radio shows called "brain trusts". These were just really smart guys sitting back and winging interesting discussions about their wheelhouse topics. VERY interesting.
Now, last downer: if you do this, you will enter into a whole new level of responsibility for your remarks. Like it or not, your commentary will begin to acquire more "weight" whether it deserves to or not. something to meditate about.
