NFL Parity Visualized
 

Found this on Reddit and thought some of you would think it's interesting (especially given the vagina graphs).

So, I get the correlation plots, but what's with the floppy vaginas?

Yeah, those are weird. I believe they're bell curves of percentage change from year to year. Then they mirror them vertically because bell curves aren't as interesting as vaginas.

Cool. A year from now, the Chiefs may well be the new "outlier of note" on the NFL graph!

Violin plot.

I have no idea what to make of those graphs. I'm not too proud to say.

Those graphs make my had spin :)

Those vaginas are telling you the nfl has a higher variance of team performance from season to season and rake the yard.

I would say the shorter season makes a difference in the NFL numbers. MLB about every team is 60-60 on the season, there is a 42 game swing normally between the clubs.

The number of contests is not important. What it is trying to convey is that NFL is more dependent on team performance than personnel.

I'd agree that from year to year the NFL does seem to have more variance... so this makes sense. In terms of postseason success though, I'd like to see some charts on that. I know we've hashed out on here before. If you go back through the last 25-30 years of the AFC... it's mostly the Patriots, Steelers, Colts, Bills and Broncos. You'd probably find as much or more championship parity in baseball, even without a salary cap.

The big problem I have with this data is it only accounts for the regular season.

If you factor in the playoffs, the MLB has the best parity the NFL a distant second, and the NBA a very distant third.

number of contest is very important

think march madness or NFL playoffs
the better team will win a 7 games series
but in the NFL any given sunday...

the ever\rygame is important
one and done makes it better
**** a play off series


hell golf is more competitive that the or three "major" sports
cause you do it now or you go the **** home

lets change base ball rules so every at bat is 3of % competition
basketball so you get 3 chances to make 2 free throws

this is not surprising information

Baseball teams in the WS since the strike:

Braves, Indians, Yankees, Marlins, Padres, Mets, Diamondbacks, Angels, Giants, Cardinals, Red Sox, Astros, White Sox, Tigers, Rockies, Phillies, Rays, Rangers

18/30 Teams

Champions since the strike: Braves, Yankees, Marlins, Diamondbacks, Angels, Giants, Cardinals, Red Sox, White Sox, Phillies

10/30 teams

NFL: Super Bowl teams since the strike:

Chargers, 49ers, Cowboys, Steelers, Packers, Patriots, Broncos, Falcons, Rams, Titans, Ravens, Giants, Raiders, Bucs, Panthers, Eagles, Seahawks, Colts, Bears, Cardinals, Saints.

21/32 Teams

Champions: Ravens, Giants, Bucs, Colts, Saints, Patriots, 49ers, Cowboys, Steelers, Broncos, Packers, Rams

12/32 Teams

Sixty percent of baseball teams have been in the WS since the strike, compared to 65 percent of football teams. Thirty-three percent of baseball teams have won it all since then, compared to 37.5 percent of football teams.

Not much of a difference.
