Here are teams 21-24. For the Rules, check back to parts 1 & 2 (linked below)...
#21 The Tampa Bay Buccaneers
Total Points: 23
Total Playoff Years: 79C, 81, 82, 97, 99C, 00, 01, 02S, 05
Tampa Bay has shot up the list since I started doing this years ago, and the last decade has pushed them from nearly dead last into the middle third of the league. All Hail, Tony Dungy and Jon Gruden as the uniform change has changed the fortune of this floor mat of the 1980's.
#22 The San Diego Chargers
Total Points: 17
Total Playoff Years: 79, 80C, 81C, 82, 92, 94SL, 95, 04, 06
With many years of decent teams that never did much in the playoffs, the Chargers have scored some points - just not as many as they would have liked. Dan Fouts and the boys never could get over the hump. But they always had nice uniforms.
#23 - The Cincinnati Bengals
Total Points: 16
Total Playoff Years: 70, 73, 75, 81SL, 82, 88SL, 90, 05
Despite 15 seasons between playoff years from 1990-2005, the Bengals used two Super Bowl losses in the 1980's to grab a decent position.
#24 - The Seattle Seahawks
Total Points: 15
Total Playoff Years: 83C, 84, 87, 88, 99, 03, 04, 05SL, 06
The Seahawks have been bad far more than they have been good, but, obviously Holmgren has the team as good as it has ever been in the history of the franchise. Once again, uniform/stadium change coincides with fortune changes.
30. New Orleans
