DENVER -- It took a thunderous pass rush to finish off the Vikings, but what else happened to key the Broncos' 23-20 win? Let's take a look back at the three keys to find out:
1. CONTAIN ADRIAN PETERSON.
Until 10:01 remained in the game, the Broncos did this. At that moment, Peterson had just 34 yards on 14 carries, and the Broncos had done a brilliant job at swarming him, with Vance Walker and Sylvester Williams consistently winning their one-on-one battles at the line of scrimmage.
But Williams was pushed out of the way by Joe Berger on the fourth-and-1, and with no linebackers or safeties in range to clean up, Peterson took off with the 48-yard run that brought the Vikings back within three points and changed the complexion of the fourth quarter.
