Sorry about the redundancy, KFITKS already posted the same thing above!
I'm pretty sure that Dienhart got this from Frank the Tank, who is also from Chicago. I wasn't going to post this because it was just another rumor, plus I was having a hard time understanding what he was saying but since you've brought it up, I'll fill you in on what little I know on the back ground of this and you can put as much stock in it as you want.
Anyhoo, this Frank the Tank posted a story the other day on his widely read blog that the Big 10 commissioner called some meeting of all the Big 10 staff there in Chicago in order to read them the riot act about some supposed leak he had read on a Big 10 message board. Frank said he had confirmation from a couple of "his sources" that this meeting did take place, in which he threatened to fire the person that was responsible for leaking the information to this drinking buddy that then posted this "inside info". Frank made the point that he thought it was interesting that this particular "rumor" was the only one that set the Big 10 guy off. Anyway, here is a link to the post that contains the supposed leaked info and it details everything that is covered in the Dienhart tweet...
