The Fall of the Cats in the NFL

As I grouped the birds in the previous post (Eagles, Ravens, Hawks, Falcons), I am now going to do the same with the Cats of the NFL (Bengals, Jags, Lions, Panthers). This viz shows the historical winning percentages. It differs from the birds in that the general trend of the cats from pre-2000 to the last ten years is overall negative, whereas the birds were mostly positive. 

I enjoy making vizzes like this, it feels like I am combining creativity with data presentation, and it is a good feeling. My favorite part of this is hunting down the right data and cleaning it up just right so that it's manipulatable.
