Here's a look at a key matchup heading into Sunday's battle between the Seahawks and Bears.
Seahawks OTs Paul McQuistan and Breno Giacomini vs. Bears DEs Julius Peppers and Israel Idonije
This is a week where Peppers could dominate if the Seahawks don't send very capable help to McQuistan's side — he's the starting left tackle — throughout the game. McQuistan is a solid technician and knows Seattle's blocking scheme inside and out from his time spent with Tom Cable, Seattle's O-line coach, when Cable was the Raiders' head coach. He has only average agility, though, and doesn't have the foot quickness to slide and mirror the freakishly athletic Peppers.
McQuistan is a journeyman and will make his second straight start at left tackle since the first-stringer at the position, Russell Okung, was placed on injured reserve after tearing his right pectoral in Week 13.
On the right side, Giacomini has the size and fiery temperament to get a push. He plays too tall at times, though, and Idonije could find ways quickly to gain leverage.
Only three teams have allowed more sacks than the Seahawks (41) this season and the Bears have the edge rushers to consistently pressure QB Tarvaris Jackson.
