The Bears' 6-foot-4, 230-pound wide receiver Brandon Marshall can't wait to go against the Seahawks' king-sized cornerbacks Richard Sherman (6-feet-3, 195) and Brandon Browner (6-4, 221) because it means more 1-on-1 matchups than he usually gets.
The Seahawks are so confident in their corners that they don't usually feel compelled to provide double-team help.

"Whenever you get a chance to play a little 1-on-1, it's exciting," Marshall said. "I've been watching film and I saw what they did against Calvin (Johnson) and Larry (Fitzgerald). They threw some (two-man) in there but, for the most part, they do what they do, and I'm excited about that."
Both Seahawks corners are facing potential suspensions for violating the league's policy on performance-enhancing drugs, but both will be on the field Sunday.
"It's different, obviously, because it's not what we call the prototypical corners," Marshall said. "They present some different challenges, but I'm excited about this matchup. I'm happy they're playing. I'm really excited they're playing. That's good for the game, and I'm ready to compete."
Quarterback Jay Cutler said he was especially gratified to see tight end Matt Spaeth catch a touchdown pass against the Vikings as a reward for all the unsung duties he performs.
"Matt Spaeth is a guy who comes to work and does his job the right way (and) doesn't ask for anything," Cutler said. "We ask him to do all the dirty jobs for a tight end (and) a fullback. He knows his position, and he corrects me on the run game after I call plays. To have a guy like that, who is just a true professional at his job, to get a touchdown like that, I was happy for him."
Spaeth barely got both feet in bounds before going out of bounds on the 13-yard TD, which was just his fifth catch of the season.
"Everybody kept asking me if I knew I was in," Spaeth said. "All I could tell them was that I knew I caught it clean; I didn't really know if I was in. Tight ends play in the middle of the field mostly. We don't get a lot of opportunities like that. The whole dragging-the-feet thing isn't like second nature to us. I just happened to get my feet in."
Guard-center Andre Gurode stayed busy while he waited for an NFL team to give him an opportunity to prolong his 10-year NFL career, which the Bears did Tuesday.
He worked out four hours a day near his home in Texas. Now he's even busier, preparing to get into game shape as soon as possible.
"Just go out there, take some reps at practice, constantly stay in the film room, learn the playbook and if they call you just be ready," the 34-year-old five-time Pro Bowler said. "If they told me to play fullback, I'd play fullback too."
