At the risk of putting words into the mouths of the "Bo-Leavers," I believe they want Bo and his staff gone, and to replace them with a better head coach who would better represent the university, who would stop the rash of blowout losses we've suffered, who would have the team ready to play 60 minutes of fundamental football every game, and who would better understand recruiting and attack it in a more effective way.
Through all the rhetoric I've read, this is the common theme. And it's not an absurd, outlandish desire. But the message gets lost in the back-and-forth we see on message boards.
