Again, the argument is not the worst performance in the Super Bowl, it's the worst to make it to the Super Bowl. Looking at the stats (I know, regular season stats mean nothing now) the Bears had better get an early lead. Although Rex had a 102.9 rating with the lead, he had a rating of 49.6 when behind. For the record, he's pretty good with a 15+ point lead (rating of 93.6)
