And you know that because he's been a great DC at at least 2 P5 schools, serving at each at least 3 years, so you know that 1 good season was not a fluke?
The less experience a guy has, the less you can know. He's never been HC anywhere. He's been at ND just 1 season. He inherited a good D at ND.
What is best about him is that he is a long time protege of Fickell, who is very much old school. But as he is lacking experience, it is anybody's guess how he will handle being HC.
I have talked up Fickell for years, but I never would have wanted UNC to risk hiring him as HC until he'd been HC somewhere else for at least a couple of years.
ND has made a risky hire. It is similar to both UNC hiring Torbush and Miami hiring Shannon. Both of those hires hurt the programs a great deal. Maybe the luck of the Irish will mean ND avoids all that bad. And maybe Freeman will be revealed as a guy who needed another couple years as a P5 DC and then maybe 2 or 3 years as a G5 HC before he became a P5 HC.
