The differences I already noticed in the offensive planning was the tempo and motion. They got out of the huddle in a hurry and kept the D line in a stance for almost 6 seconds. There was motion on almost every play.

The routes of the Wrs seemed to be timing and beyond 10 yards.

The screens, chips and combo blocking on the DEs allowed street Fa and practice squad Ts to block a couple of pro bowl caliber ends long enough to get Wrs breaking open down feild.

The FB handoffs on the 1 yard line is one of those things that Billick did not do enough of.

There were about 4 tripple option action fakes on run plays in the first half. The FB handoff worked because the Rb and QB carried out a great option fake on the edge allowing Grubbs and Brown to maul the guys in front of them 1 on 1.
The details make all the difference. If you have a defense off balance and guessing, you can beat them without all pro talent accross the board. If the D knows what you are doing and have a few mismatches, they can shut down even Manning or Brady.
