• Attack the blitz. The Seahawks successfully pressured the 49ers in their initial meeting by using five and six-man pressures. The 49ers must be ready for the pressure and attack it by hitting their receivers on quick slants and fades before the rush arrives. Look for more three-step routes to counter the Seahawks' blitz-heavy game plan.
• Lock 'em up. Walt Harris and Nate Clements haven't played up to expectations, but have the talent to smother the 49ers' receivers. With the Seahawks relying on the pass, the 49ers' duo must step up and handle D.J.Hackett, Bobby Engram and Nate Burleson in man coverage.
• Put the game in Hasselbeck's hands. The Seahawks' inability to run the ball consistently and ShaunAlexander's injuries will force Mike Holmgren to put the game in MattHasselbeck's hands. Look for the Seahawks to ignore the run and come out throwing against the 49ers' vulnerable defense.
• Turn up the heat. The Seahawks successfully pressured and harassed the 49ers' quarterbacks in the first meeting by relentlessly blitzing off the edges with Julian Peterson and Darryl Tapp. Don't expect that game plan to change with San Francisco's offense surrendering almost four sacks a game.
