Mark and Colorado, I understand your points, and I will confess to being an idealist. However, I would not compare the JC "greener pasture" move with SP's similar move. If memory is correct, SP was at NDSU for about ten years -- first as an assistant and then as head coach for the last seven years. From his statements -- both publicly and to me personally -- since his arrival he is looking for stability and will put the program needs ahead of his own personal ambitions. He seems cut from a different cloth than our previous two coaches.
When he left NDSU he left them in good shape with a stable program. Evidence of that is that they named an assistant (associate head coach, I think his previous title was) as the new head coach very quickly after Saul left. It was, from what I can tell, a head coaching-in-waiting kind of situation. In terms of salary and the pursuit of money, Saul said in one recent interview something along the lines of "how much money do you really need to be happy." The general context of the remark was implying that he now has more money than he ever dreamed of and that at some point the pursuit of more cash would be kind of vain. I think Calvin Coolidge would have liked Saul!
Edit: I think it's funny that on at least one of the BC boards some are saying that Ohio got the better end of the deal and they would be happier with Saul than with JC. So, maybe things have worked out for the best in the long run. I do agree that some folks will become philanthropic with extra cash and that's a good thing. I suspect that JG is that kind of guy, and maybe JC too, for that matter. But I can also say that SP left the NDSU program in better and more stable shape than JC, and to a lesser extent JG.
