You guys wanted Quinn after that 28-3 embarrassing loss to the Patriots?
I personally don't really want Quinn and I'm not sure where the fascination for him comes from. He wasn't a horrible HC, but he wasn't exactly great either. He was just a middle of the road guy. After Shanahan got his HC gig in San Fran, his teams looked mediocre. I will say this though, I liked how he let Shanahan just do his own thing. He stayed out of his way and focused more on his specialty.
One thing about Quinn is his situational football was garbage. People complain about Carroll in this regard, well Quinn was even worse.
I get it, Quinn has proven time and time again he is an elite defensive coordinator in the NFL. In fact, he may even be the best defensive mind in the game right now. He's very adaptable to the players he's given and he isn't beholden to any one scheme.
In Seattle he ran Pete's defense to perfection. He was probably the most aggressive as far as things like stunts, and blitzes were concerned. He was definitely the best coordinator that we've ever had.
All that being said, being coordinator and being an HC are two very different things. There is reasons why elite coordinators often times flame out as HC. Think guys such as Josh McDaniels and Fangio. They're were both at the cutting edge as coordinator, but why did they fail? The simple truth is they lacked the ability to put together a program and manage big personalities.
X's and O's are not the most important thing as HC. You have to be able to manage many moving pieces to create a cohesive unit. This is what Pete Carroll is great at. He's fantastic from a managerial standpoint, maybe even might be the best in the NFL from this aspect. He knows how to craft a program and get people to buy into his ideas. If there is someone that doesn't, they're just let go ala Percy Harvin. He understands the psychology of his players.
This is the jump people have to make in order to be a successful HC in the NFL. Few have that ability, even some of the greatest minds in the NFL from an X's and O's standpoint.
I'll leave with this -- people have to let go of 2013. It was a great memory for us, and we will always cherish it. If Carroll ever makes it back to the Super Bowl that team will look vastly different from the LOB team that brought us a Super Bowl. People are always putting things on the 2013 timeline "oh we're at 2010 right now" or "it'll just take two years for Carroll to revamp the defense" or "Quinn will bring us back to the glory days".
Sorry, that team is just a memory now and any future success will look very different whether Carroll is leading that team or not. It's like lusting after an old flame.
