You didn't answer the question, but I'll play along.
It's not a "he said, she said". It's a "he said..." Only one side of this story has come out, and you are the one using that to bash the staff. I have yet to assert, as fact, that the staff told him he only had a conditional offer.
There are many possibilities. Maybe he was told from the beginning that he may have to blueshirt if numbers got tight, which is supported by the fact that he never visited campus. Maybe Memphis started pressuring him to flip, he told the staff he wanted to visit, and they told him he'd lose his offer if he did. Maybe Butch decided that Hart didn't improve like they projected, and Shoop didn't see the potential Jancek did, and they decided to rescind or alter the offer.
It's likely we'll never get the true story in its entirety. Unless we do, all we can do is look at the facts as they are presented and make our own inferences. You've decided to use this as a stick with which to bash Butch and the staff. I've decided to keep an open mind.
I answered your question. Now, I ask again, what proof did you use to arrive at your conclusion?
