He does call the plays on offense, which is what I think you meant. But there is so much more that goes into offense or defense than just calling the plays on Sunday. The coordinators are a big part of that. I don't know much about this guy. He looks slightly bad ***, so I guess that's a good start
I have zero opinions on the guy. Sounds like a decent hire as far as I can tell, but the main reason I'm going to be behind him for a season or 2 at least to give him a chance, is the guys at the top work hard. They usually get it right. Not always, they aren't perfect, but they aren't stupid and didn't get to where they are because of Aaron Rodgers. Life is full of 2 way streets and they had as much to do with getting #12 to where he is today as #12 has helped this team. They may have gotten this wrong, but what I do know is they have their plan, they put a lot of work into it, they know the direction they want to go and they're doing what they think they can with who they have to get there. also contrary to popular belief none of these guys got to where they are because they're stooges or somebody's kid. They got there by proving themselves and hard work.
So until we get a chance to see a defense on the field and give them a chance to learn it and grow in it, people are going to have to give me some pretty damn specific reasons why I shouldn't support a guy they hired and it needs to be a lot more than a defensive ranking for a team when there are rankings from another team on the contrary. Unless you have details from every game and a lot of situations in terms of personnel available, offenses faced and specific calls made that contributed to that ranking, it's just a meaningless stat about a team that has been terrible for a long long time.
