The disadvatange dome teams have is that they inevitably have to play in bad weather when it counts the most. Also, it seems like most dome teams are offense first, pass first. St. Louis proved that a dome team could win the superbowl but they could run the ball when they had to. Didn't St. Louis prove a dome team could win the Super Bowl because they had HFA and played the Super Bowl in a dome as well? They went 8-0 at home, and 5-3 on the road, with 2 of their road wins coming at the Georgia Dome and the Super Dome. So they only played 6 non-dome games all year and went 3-3, while playing 13 dome games and going 13-0. Oh and their 3 non-dome wins were against the 4-12 49ers, the 4-12 Bengals, and the 8-8 Panthers.
