After correctly predicting the Super Bowl winner 90 percent of the time over a 20-year period, the Super Bowl Predictor System is ready for mothballs.

Why is that?

Just like many of you, I am a fan of a specific team. I haven’t missed a Chicago Bears game since the start of Walter Payton’s career. In January of 2007 the Bears were going to the Super Bowl. The Super Bowl Predictor System said the Bears were an overwhelming favorite. The Chicago media was all over this.

Except, Peyton Manning had something to say about it. Despite an opening kickoff return for a touchdown by the Bears’ Devin Hester, Manning led the Colts to an upset victory.

I should have quit while I was ahead. That Bears' Super Bowl launched a performance slump where the Predictor System has missed five of the last seven Super Bowls. The overall record of the system is down to a 64 percent success rate. Not horrible, but with its recent record, here’s what I have to say: Sayonara.

For those of you who still want to know what the system says, it says that Manning is going to lose again. But I ain’t gonna bet against him a second time. The Seahawks won 7 of the 12 predictors, with two going to the Broncos, and three ties. The details:

For old times sake, here’s how the system is designed to work. Each of the 12 predictors predicts the Super Bowl winner correctly 53 percent to 64 percent of the time. When taken together they have a greater success rate. However, now for the first time since we started the system, there is one stat that is just as successful as the 12 indicators put together. It’s Fewer Opponent Total Yards, which has predicted the winner 30 out of 47 times (64 percent). This too suggests that the Seahawks, the better defensive team, are going to win.

I’m picking the Broncos.
