Jaguars' Game Plan

• Stick to the formula. Jacksonville inexplicably deviated from its smash-mouth game in the first meeting with the Colts. But expect the Jags to stick with the formula in the rematch. Look for a steady diet of power runs by Fred Taylor and Maurice Jones-Drew to set up a few deep shots to Reggie Williams and Dennis Northcutt off play-action.

• Turn up the heat. The Jags are primarily a two-deep team, but they have tweaked their scheme to feature more five-man pressures in passing situations. With the Colts' offense succumbing to pressure in recent weeks, look for Jacksonville to turn up the heat by calling more blitzes early in the game.

Colts' Game Plan

• Feature the draw. Joseph Addai's emergence has given the Colts' offense an effective counter to increased blitz-looks they have faced this season. With the Jags revving up the blitz packages, look for Indy to give Addai several carries on draws and delay to take advantage of the up-field rush.

• Keep Bob Sanders in the box. The Colts will eschew their standard two-deep look in favor of more three-deep zones to involve Bob Sanders in the rush defense. By dropping Sanders in the box, Indy should always have a free hitter available to help slow the Jags' third-ranked rushing attack.

Detroit at Minnesota

Lions' Game Plan

• Back to attack mode. The Lions have lost their offensive rhythm and have failed to aggressively attack their opponents out of their four-receiver sets. But look for Mike Martz to jump start the spread formation against the Vikings' two-coverage by throwing quick option routes to Mike Furrey and Shaun McDonald before connecting with Roy Williams and Calvin Johnson on deep crossing routes.

• Eight is enough. The Lions held the Vikings' potent rushing attack in check in their first meeting by keeping eight-men in the box on most downs. Given their success in the initial match up, look for Joe Barry to frustrate the Vikings with an assortment on zone blitzes and three-deep looks on most downs.

Vikings' Game Plan

• Beat 'em up with the 1-2 punch. The return of Adrian Peterson adds more punch to the league's top-ranked running attack. Expect Brad Childress to hammer the the Lions with an assortment of outside zone runs featuring Peterson and Chester Taylor.

• Turn up the heat. The Lions' pass protection woes will lead Leslie Frazier to keep up his blitz-happy tactics on early downs. Expect to see lots of five- and six-man pressures from the Vikings as they aggressively come after Jon Kitna in the pocket.

San Francisco at Carolina

49ers' Game Plan

• Gore, Gore, Gore. The 49ers' return to the win column was keyed by Frank Gore's breakout performance (214 total yards and two touchdowns). Expect San Francisco to continue to ride Gore against Panthers' disappointing defense.

• Be aggressive. The 49ers will challenge the Panthers' inept offense by bringing pressure from all angles. Look for Patrick Willis, Tully Banta-Cain and Michael Lewis to have plenty of chances to get after the passer on an assortment of blitzes.

Panthers' Game Plan

• Use a simple attack. Carolina's offensive woes will lead Jeff Davidson to simplify his offensive attack to get more out of the team's playmakers. Look for the Panthers to lean on the quick-passing game to get Vinny Testaverde and Steve Smith untracked early.

• Snuff it out. The Panthers must stop the 49ers' running game by using eight-man fronts to limit Gore's running lanes. By stuffing Gore early, the Panthers will be able to aggressively pressure Trent Dilfer in the pocket.
