Ferentz has 3 big plusses in his favor
1. he has NFL coachiing experience under Bellichek in Cleveland
2. he was the offensive line coach which helps in 2 ways
a. he will have the juice and the understanding to make the OL a priority on draft day
b. he won't tolerate teh dysfunction regarding zone blocking, drive blocking, blitz calls, etc
3. he has proven capable of running the entire program at a major college - the major unknown of most NFL coordinators
