It was Sept. 8, 1985, and the Chicago Bears had just given up 28 points in the first half of their first game of the season.
They trailed Tampa Bay 28-17 at home when a cornerback named Leslie Frazier changed the momentum of the game, and perhaps an entire season.
Frazier intercepted Steve DeBerg, who had been having his way with the Bears defense, throwing three first-half touchdown passes. Frazier went 29 yards the other way, scoring a touchdown as the Bears rallied for their first of 12 consecutive wins.
Those who remember the Bears team that went 15-1 en route to winning Super Bowl XX probably forgot that Buddy Ryan's defense gave up four touchdowns in its first two quarters of the season. That's because most of us consider that defense the best we've seen in our lifetimes.
It's also hard for us to fathom that this year's Bears defense might be even better than the 1985 version. That's something that Frazier, now the Vikings' head coach, and his staff, which includes former teammate and Hall of Famer Mike Singletary, get to face twice over the next three weeks.
It feels strange comparing any defense to the 1985 Bears, particularly before season's end. After all, Buddy's boys finished things off by shutting out the Giants (21-0) and Rams (24-0) before blasting the Patriots 46-10 in the Super Bowl.
However, through nine games ... well, you be the judge.
