Until the Rams won the Super Bowl, the line was dome teams couldn't win it all because they weren't tough enough to play in bad weather conditions. After they defated Tennessee, it changed to dome teams can only win the Super Bowl if they secured home field advantage throughout the conference playoffs, so they never have to play in bad weather conditions. Minnesota didn't do much either towards disproving that theory today, so now it's just Michael Vick and the Falcons who have a chance to show they can actually play outside in a January conference title game and win.
