The head coach is responsible for people he hires. Now, not completely clear if he hired Quinn or if that was done by Jerruh. I agree Quinn failed in the big games and has the most game to game responsibility.
And most of the time the head coach doesn't have the final say that would be the GM and the ownership that actually hire most of the coordinators so let's let's be clear.. But don't get it twisted Jerry's not the only one that hires the coordinators for his head coaches I found out from some eagles fans absolutely Howie Roseman does all the hiring of all the coaches including the assistance I'm sure he has input from his head coach but you got this backwards I mean owners hire their own CEOs and then the CEOs hire their employees but coaches head coaches and coordinators are more like CEOs of a business and usually the GM and the owner but mostly the GM but in this case is both make styles final hires they're the ones who approves and disapproves and they're typically have the final say and not always in agreement with the head coach...
And by the way if you think that's a bad thing from what I hear Mike Nolan was 100% Mike McCarthy hire, he failed big jerry ate that deal, so why wouldn't jerry make the final on Quinn which at times is the best way, but he was better than mike nolan..
So, this is a group effort it's not just the owner not just the GM and not just the head coach there's a there's a lot of meetings that happen in order to do this but most GM of most teams do all the hiring of the coordinators.
That is why I have to laugh sometimes I realize Howie Roseman has some great standing in here is one of the greatest gems ever lived just because he makes a bunch of moves doesn't make it great moves they failed last year they folded they blame the coordinators that they changed out from the Super bowl year so they change them out again and does it look that improved so that would be on Howie Roseman right and a little bit on the head coach...
but did you notice...
The Jets fired their head coach but didn't fire the coordinators, what does that tell you it tells you the gyms and the owners are making these decisions for the most part but there are times where there is input and that the coach decides...
