I just took a look at the chatter on a few Clemson boards. They are delusional. Many seem to think that Golden is theirs if they want him, though some apparently think he isn't worthy of the position because Clemson "exposed" him when he was the head coach at Miami. Now that's precious. It was like the guys here saying we should just go after Nick Saban or Urban Meyer. Total fantasy.
I cannot imagine money will be an issue; Freeman and Bevacqua will make sure Golden is paid whatever is needed to keep him at ND, assuming Golden decides he wants to remain a DC in college. And why would Golden want to move over to a program that may be in a downward trajectory (Clemson) for one that is moving up the scale? To be sure, Clemson is still a very good football program, but the bloom is off the rose from where they were 5 or 6 years ago.
From articles I have read on Golden he seems to really like the culture at ND, and I also read his son is attending ND, though I have not attempted to verify that. If Golden moves on, it will be because he is offered a DC job with an NFL team, or a college decides to offer him a head coaching position. He ain't going to Clemson to become the new DC there.
