The 1985 Chicago Bears were good at keeping opponents to donuts on the scoreboard. En route to ultimate glory in Super Bowl XX, the Bears shut out four teams -- including two in the NFC playoffs -- behind one of the strongest defenses in league history. The Bears shut out the Dallas Cowboys and Atlanta Falcons in consecutive weeks during the regular season, and then shut out the New York Giants (21-0) in the divisional playoffs and Los Angeles Rams (24-0) in the NFC Championship Game. The Bears were the first team to hold opponents to back-to-back donuts on the scoreboard in the playoffs.

Perhaps the Bears' most important "donut" of that 1985 championship season was its first. On national television, the Bears dismantled the Dallas Cowboys, 44-0, in Texas Stadium. The epic beat down -- the most lopsided loss in Cowboys history -- made the cover of Sports Illustrated, and the game was a seminal moment in the Bears' season. With the Bears improving to 11-0, everybody was now taking this team seriously as a title favorite.

The AFC posted a giant donut in Super Bowls for 13 consecutive years. The conference's best representative was routinely manhandled by the NFC's best, a collection of teams that would rank among the greatest in league history (such as the aforementioned Chicago Bears, Bill Walsh's San Francisco 49ers, Bill Parcells' New York Giants and the Dallas Cowboys of the early 1990s). Posting the biggest donuts were the Buffalo Bills -- who were 0-4 in Super Bowls -- and Denver Broncos -- 0-3 in Super Bowls during that streak. It was the Broncos that finally ended the AFC's misery in 1997, upsetting the defending champion Green Bay Packers in Super Bowl XXXII.

The most lopsided game in NFL history occurred in a championship game between the Chicago Bears and Washington Redskins at Griffith Stadium in Washington, D.C. The Redskins had zero answers for a modern pro set offense that would -- in years to come -- dominate the landscape of pro football. Using a "T" formation scheme devised by Bears coach George Halas and mad-scientist innovator Clark Shaughnessy, the Bears claimed their fourth of nine total NFL championships.

In a 1994 NFC wild-card playoff game, the Green Bay Packers held Pro Football Hall of Famer Barry Sanders -- a running back with a seemingly endless collection of awesome highlights -- to zero yards rushing. In fact, Sanders went for minus-1 yard on 13 carries in a 16-12 loss at Lambeau Field.

For more than 40 years, a team of college football all-stars would face the defending NFL champions in a preseason game in Chicago. In 42 games, the defending professional champions won 31 times over the college all-stars. However, at the end of this game's run, NFL teams dominated. The NFL champs won 12 consecutive, with the 12th matchup signaling the end of this four decade old tradition. The Super Bowl X champion Pittsburgh Steelers hammered the college all-stars, 24-0, in a game that was called late in the third quarter due to heavy rain. That donut wasn't the only reason the game was discontinued. Spiraling costs to host the event ultimately doomed it to become a footnote in football history.

86 times during the Super Bowl era (since 1966) a quarterback has posted a donut for a passer rating. This list includes six Pro Football Hall of Famers (Bob Griese, Johnny Unitas, Len Dawson, Terry Bradshaw, Joe Namath and Warren Moon), and one quarterback sure to be enshrined in Canton once eligible, Peyton Manning. Manning's donut passer rating happened in the Broncos' 29-13 loss to the Kansas City Chiefs last season. Manning completed five of 20 passes for 35 yards with four interceptions before leaving the game with an injury.

Nobody owns the double zero number quite like Otto, who wore his two-donut number for 15 seasons with the Oakland Raiders. Toiling in the trenches as one of the greatest centers in league history, Otto was a vital part of the Raiders' rise to prominence in the late 1960s. Otto was elected into the Pro Football Hall of Fame in his first year of eligibility.
