Having a plan for offense and defense.

All do.

Some excel and some simply can't. (For myriad of reasons).

But the really good ones make it a point to create mismatches, put defenses in a bind and call a play to set up the next play. Some of the neatest stuff I've seen is when an OC calls a play with a specific formation, gets a defensive look he wasn't expecting and later in the game calls same play, but on sideline adjusts a route or two to take advantage of that defensive scheme.

Sean was a master of this. Shanahan in SF. McDaniel in Miami. Some OCs just see the chess board differently than others and it makes them special.
