Then how about you look at it from this point of view. We are most like;y going to have to groom a young QB to run this team in the next three years, either from on contract or through the draft. How about we look at a person that capable of understanding the young guys and teaching them how to play great?
To be fair, any coach that isn't in the business of understanding young (all) players and teaching them how to play (great or otherwise) probably isn't coaching in the NFL in the first place.
A lot of fan talk on coaching topics is very polarised into coaches that are great and everyone else being some kind of bum. In truth these are some of the best in the world at coaching. I appreciate the natural desire to contrast and compare the options out there, but the margins are much smaller than that. Seek 'the best' options, for sure, but don't unnecessarily denigrate 'the rest' in the process.
