Jim Strong is the last OC at Notre Dame to win a National Championship. So based on that Lou Holtz has been the only coach who had an effective hire for OC. Here is a direct quote from Jim Strong:
“I think Marcus Freeman knows what he wants to do,” Strong said. “He's a great football coach, and he’s going to look at those individuals, and whoever ends up with it — what an honor and an opportunity to work at one of the premier institutions in the country with not only great players, but great young men.
“I follow Notre Dame football enough to know that he has a lot of qualified candidates. And I believe he’ll make a great decision.”
I have no idea if this is going to be a good or bad hire, but I cannot go against what Freeman has done so far with hiring HIS Staff. I truly hope that Parker has success and that ND does its due diligence when hiring the next OL coach.
