By air or by land: The biggest question on offense is whether offensive coordinator Mike Martz will follow common sense and run the ball against the worst running D in the league, or stubbornly stick with the season-long gameplan of having Jay Cutler pass on the majority of plays.
Rest for the weary: Though the Bears have the second-best defense in the league, they are still beat up. Lance Briggs has missed most of the last two games with an ankle injury, but feels revitalized for Sunday. Brian Urlacher has allowed nagging groin and thumb injuries to heal, so the linebackers should be at full strength.
O Canada: Sunday's game in Toronto will be a homecoming of sorts for the Bears leading sack-man, Israel Idonije. Though he was born in Lagos, Nigeria, Izzy started his football playing in Manitoba and though on the road, he expects to play in front of family. He's having the best season of his career, so hopefully he'll put on a show for his loved ones.
To their health: Offensive lineman Roberto Garza and safety Major Wright are expected to play this Sunday after dealing with injuries. Garza's return should bring stability to the O-line, while Wright will add depth to the Bears less-than-stellar secondary. On the flip side, cornerback Zack Bowman is not expected to play on Sunday because of a foot injury.
Father-son game: Bears defensive assistant coach Gill Byrd will be up against a familiar player. His son Jairus is a safety for the Bills. Gill said that he wants his son to have the best game of his career in a loss. If Cutler plays like he did against the Redskins, Jairus has a chance to make his father happy.
History lesson: This will be 11th time the Bears and Bills meet on the field. The Bears have a slight edge on the series, leading 6-4. The Bills won their last meeting in 2002.
