The Divisional Playoffs start in the NFC, in San Francisco with a game between the New Orleans Saints and San Francisco 49ers. The St. Louis Rams played both of these teams, beating the Saints in what might be the flukiest upset in the NFL this season. There's another connection here for Rams fans, with Saints DC Gregg Williams reportedly going to join Jeff Fisher in St. Louis.

Watch Williams defense in this game. Drew Brees and the Saints offense gets most of the pub these days, but Williams will be working to make life tough for Alex Smith ... I like him already. New Orleans has a really poor pass defense this season. They led the league in blitzing as well as dropping eight into coverage, as a means of compensating. Keep your eye on how Williams works against this team and try to imagine him working with the Rams against this same team next season.
