I actually heard this rumor prior to Henning saying it; which scares me a little. But my better judgment says that it is very unlikely. I can't see them doing this prior to the biggest game on the schedule. I also can't see Brandon going to the kids after they upset OSU and saying, "oh by the way I'm firing RR".
I'm chalking this one up with the Gerg resignation rumors. It may be what some people are hoping for but it's probably far from the truth.
