For the first playoff SEC Network had the LSU Radio feed over the game broadcast.
For the second playoff ACC Network has the Clemson radio feed over the game broadcast
GoalLine/Bases loaded has a "Data center" feed with stats on the screen all the time. One great feature of this channel is it offers the ESPN Radio broadcast as opposed to the ESPN TV commentators.
The Skycam feed with the "live" stadium audio is awesome too.
