1) He had no previous Head Coaching experience in the NFL (YORKS love this).
2) He had no proven winning record in the NFL (Yorks approved).
3) He doesn't know anything about offense (Perfect York hire).
4) He came cheap (Did I mention cheap).
5) He is an internal candidate. Yorks love this. They don't have to go outside the organization on a long Head Coacing search. The fastest, easiest, cheapest internal hire is the pattern usually.
