NFL Coaching

I came across this article by Bryan Broaddus on DallasCowboys.com:

Broaddus: Coaching Staff...

Sounds as though the Cowboys may have upgraded their coaching positions such as Running Backs and Tight End Coaches, but most of all of course with the full change out of Defensive staff with the switch from Rob Ryan's 3-4 Defense to Monte Kiffin's 4-3 Tampa Two Defense.  I think in today's NFL, with all of the parity in the league with regards to players, coaching provides a significant advantage or disadvantage more than it ever has.  If you've got a good QB, then the next most important thing is coaching... and not just the Head Coach, but the entire "team" of coaches.
