New York Times readers, let me introduce THE SYSTEM. That, of course, is the infamous rule that Southern/dome teams struggle when playing in a colder climate after October 31. But wait, you say, THE SYSTEM hasn't worked very well this year. I've got three words for you: abnormally warm autumn. So instead, we checked out records by kickoff temperature rather than date. Since 2000, dome teams are 15-41 when the kickoff temperature is 50 degrees or below -- and 2-13 when the temperature is freezing or below.
