I am not blown away by any of the names mentioned. My negativity has been born out of Jack's history of hiring and his complete mismanagement or incompetent oversight of the Notre Dame baseball program. Even worse, Jack has appeared to not give one damn about the success of the Notre Dame baseball program.
so he does deserve some credit for assembling the roster that made it to the last game of the CWS. I don't know how good of a head coach he would be, but he was a college teammate of their head coach Bakich and has coached with him for years. I suspect that he would recruit well and at least coach the fundamentals soundly.
For that matter, ND is be more southern than Michigan.
