You misunderstand, I didn't say they weren't interested, I said he didn't have commitable offers from many of his top choices. Many of those schools had backed off and were recruiting other players at that position. Nebraska being one of them. If he was a priority to those other schools, he isn't deciding between TCU and Minnesota. He can list all the final 6's he wants, that doesn't mean those schools were ready to take his commitment on his time frame.
Of course the school is going to allow him to spend his own money to come to their campus. Why would they care?
