I'll line it out plain and simple. Nolan's scheme is A-Typical. What does that mean? It means that few, if any, other teams run it. How does that effect us? You have to have unique personnel, specific skill sets at key positions in order to make it work. How does that translate? It means that a team that settles on Nolans brand of Defense will have to have whole sale changes to make it work and more importantly, will have to have whole sale changes when they get off of it. why is that important? Look at Nolan's history. Has he ever been anywhere for more then 3 years or so? What does that mean? It means that if you want Nolan, and this is really why this was a poor choice in my book, you have to accept the fact that you are going to have to invest in serious roster change to bring him in and, unless you can get somebody who runs a very similar system and is good at it, you are going to have to take those investments in personnel and **** can them in a few years because it's likely you will be changing schemes again and Nolan's personnel, won't work with a new scheme.
I really don't like the hire but hey, it's done now.
