The advantage goes to a quicker ballclub, and that's why teams like Atlanta play better in domes. The Falcons' defensive line is built for speed. On artifical turf, there are no chances of your foot sliding out from under you. It allows you to use optimium power and strength in your legs. Dome teams haven't played well in Super Bowls because during the regular season, they throw and kick in a perfect environment.
Teams tend to draft players from the same environment they've played in.
And dome teams have to go undefeated at home and win two on the road to be 10-6 and get a playoff berth. That's the thought process of coaches when building a team. And you're very observant in realizing the similarities. We were a team that based its performance on John Riggins running the football. In that Super Bowl, the Raiders did a great job of controlling our center and two guards, and we weren't able to run the ball effectively.
