Perfect is good, but some things are perfectly bad. The National Football League has five perfect teams which is great if you're into math and the power of zero. You have the Denver Broncos and the Kansas City Chiefs who are perfectly good after yesterday's week six games (on October 13, 2013): they're undefeated at six wins and no losses. There's a portion of people who consider that perfect: it seems reasonable to them. On the other hand there are three teams who haven't won (after week six) a game yet. They are the Jacksonville Jaguars, the Tampa Bay Buccaneers and the New York Giants. They are considered perfect: perfectly awful.
Perfect zeroes after week six games
We know that bad teams have different levels of badness to coin a new word. The Jacksonville Jaguars are still the worst team in the NFL (after yesterday's 16-point loss to Denver) based on perusing the numbers. They are now 25th in offensive passing yardage and 32nd in rushing yardage which was their strong point last year. They've given up 198 points while scoring 70 points. They have genuine badness according those numbers.
Also without a win but not hopeless (because they have Eli Manning at quarterback) are the New York Giants. They've gotten to zero wins by being 8th in offensive passing yardage and 30th in rushing yardage. Eli's Giants have given up 209 points while scoring 103. They have badness but not Jaguar badness.
Tampa Bay is the best of the worst and have reached zero by unfortunate circumstance: they lost games this year by one, two and three points. Their offense has been pitiful as has Jacksonville's. The Buccaneers are 32nd in offensive passing yardage and 19th in rushing yardage. Tampa Bay is frugal on offense and defense. They have given up just 101 points while scoring 64 points.
Perfection is loud and easy to hear if it's perfectly good: everyone knows how great Peyton Manning is. His Broncos are still (after the week six games) 1st in offensive passing yardage and 15th in rushing yardage. They've scored an insane 265 points this year while giving up 158 points which is a lot. Consider, though, they've won by an average of 17.8 points/game.
Kansas City got a renewed vigor this year when Alex Smith took the helm at quarterback, but their overall strength has come from a stifling defense. The Chiefs are 26th in offensive passing yardage and 15th in rushing yardage. Kansas City has given up 65 points while scoring 152 points.
