Here is the run down after listening to all three as of 4:30 today, prior to the game tonight. (I think this a fair representation of their day to day shows throughout the year too.)
Query and Schultz
Far and away the best analysis and unbiased discussion on the game. Good points regarding both teams. Both guys are IU grads but don't come off as homers.
Kent Sterling
Holy hell. This is the ultimate IU homer show. Move along, nothing to see here.
JMV
If he can focus long enough to talk sports, isn't too bad. His problem is that he has fallen too in love with himself and thinks everything he says is cute, funny and that everyone wants to talk about 80's pop culture. Mixed bag about the game tonight.
