A new low in Seahawks-49ers rivalry

February, 2, 2011
Thank you, Seahawks fan Shane Rego, for pointing me toward Football Outsiders' in-depth look at the 1992 NFL season.

Football Outsiders' statistical analysis has revealed the Seattle Seahawks' infamous, notorious, sulfurous 1992 offense to have been even worse than the San Francisco 49ers' historically, hysterically inept 2005 version. The analysis compares each play during a season with similar plays for every team in the league. The resulting metric, termed Defensive-adjusted Value Over Average (DVOA), generates positive or negative percentages. Negative percentages are bad for offenses and good for defenses.

"The Seahawks' minus-45.9 percent offensive DVOA sets a new FO record, surpassing the 2005 San Francisco 49ers (minus-42.0 percent) as the worst offense we've ever tracked," Football Outsiders reported. "It gets worse if you isolate the passing game from the running game."

The 2005 49ers' pass offense was the worst on record since 1993 at minus-57.9 percent. The 1992 Seahawks' pass offense came in at minus-71.0 percent. The chart breaks down passing stats for the quarterbacks on those teams' rosters. The seven players combined for 17 touchdowns, 44 interceptions and a 41.7 rating.

While justifiably ragging on Seattle's 1992 offense, Football Outsiders acknowledges the strength of its defense, which ranked third in DVOA that season thanks largely to AFC Defensive Player of the Year Cortez Kennedy. I'll have more on Kennedy as Hall of Fame voting approaches. I consider him to have been the best, most complete defensive tackle of the 1990s, when counting Reggie White as a defensive end.
