To me McDermott, after reading up on him the last few days, checks almost all the boxes that I would want from a HC:
1. Has he been successful (recently) at his craft or specialty? Yes.
2. Has he been around the NFL long enough but is still considered young/up and coming? Yes.
3. Is he not a retread? Yes
3. Does he come from a good coaching lineage? Yes
4. Is he a leader? From everything I've read, Yes
