One major question I have: how much experience does Greg Brown have with the 3-4? It seems to me, that is what needs to answered moreso than the hiring of McGhee. If you are going to hire a guy with little experience as coordinator, would you want to compound that by giving a defense he has little experience running?
I really do not care either way, just pick something. The muddled front seven situation mentioned above is exactly right. I thought the "hybrid" defense under Hawkins was a disaster at times.
