Given this level of speculation, the only conclusion one can draw is that Kelly's agent, or BK himself, has been talking up his interest in an NFL job, and of the 'restrictions' at ND.
With that said, there can be no more future for BK at ND. The negative recruiters will have a field day with this, and what coaching assistants would want to get involved with a program that could blow up at any time.
JS needs to get this house in order. I suspect there's going to be plenty of drama over the next few months.
