So we go from a coach who didn't believe in the concept of practice to one who has no scheme or game plan, what do candidates and Bidwill discuss in interviews? Anything but football?
FWIW, defensive football "plays" always seem weird to me. The offense really dictates so much; they know what they're going to do. The defense has to respond to what the offense is doing or rush heedlessly into nothing.
I don't really pretend to understand much about football plays at the NFL level, but I'm guessing it's a lot like Pete Carroll's "rules" where the DC is going to push personnel and formation and the players know what to do and how to react based on the lineup and action.
This has benefits because the defense can never be wrong; they're always responding with the "perfect" answer, but if one or two guys don't follow the rules or get crossed up, it can be a real disaster.
