We learned that when BB smells blood, the other team is in deep doo doo. With the onset of snow, BB knew two things:
1. Tennessee's pass rushers were going to have trouble getting solid footing to mount a serious rush. See the famous Snow Game. The Titans already had a lousy pass defense, but this was going to make them completely ineffective. Lots of shotgun and play-action was in order.
2. In the snow is a great time to play tight man-to-man. The receivers are not going to make the crispest of cuts. The QB's footing is going to affect his mechanics. BB was forcing the QB to be perfect on every throw, something difficult to achieve in these conditions.
The Pats played the weather perfectly. Compounded with Tennessee's quite visible flaws, this added up to the 59-0 shellacking.
