Prefer type of coach? An offensive, A defensive, or a middle guy?

I'm going against the grain and say defensive minded coach. I like what I see with Kubiak and the coaches that followed him here. An offensive coach would surely bring in his own people and completely start over. The defense needs a new blood. Pass rush is still an issue, running QBs are still an issue, run defense is abysmal.
I wouldn’t hate a defensive coach, I would love to see a 3-4 defense again. There are only a few 6’6” 270 pound DEs that run a 4.45, but there are a lot more 6’2-4” 250 pound linebackers that can run. Rickey Jackson and Pat Swilling were 6’2 and 6’3 about 250. I want the old Dome Patrol!!!
