It's annoying that he seemingly hasn't learned from the first time he did this, but I honestly think he was just trying to answer the question and he's not mature enough to give the more political answer. Certainly didn't sense any disrespect towards Ty, but you just have to brush off the Nebraska portion of the question and talk about your current team. Hopefully TK is telling him as much in private while defending him publicly, which is what a good coach would do.
