Keep your eye on ...
John Carlson's emergence: The second-year tight end out of Notre Dame has become a force for the Seahawks. He led the team with six catches for 95 yards and two touchdowns last week. He may not find it as easy to put up similar numbers vs. the 49ers and their stellar linebacking crew, however.
Shaun Hill's moxie: San Francisco's starting quarterback does not possess immense physical skills or highlight-reel ability, but he wins (8-3 career record as a starter). Perhaps his greatest attribute is his competitiveness and that is exactly why Singletary, known for his fire and passion, picked him to lead the team.
Nate Clements' ball-hawking skills:Seahawks QB Matt Hasselbeck has thrown 12 interceptions in his last eight games and often takes chances with the ball. After coming down with a pick last week, Clements will have confidence and should Hasselbeck give him a chance, the former Pro Bowl corner has the hands to add to his season total.
