[OC] Metro size vs number of big 4 US sports teams

Raw data: [https://docs.google.com/spreadsheets/d/1Xppl1dCi3yKi1oHrdnHqC1cMeXg5\_D2EY5e9gosnxKE/edit?pli=1&gid=0#gid=0](https://docs.google.com/spreadsheets/d/1Xppl1dCi3yKi1oHrdnHqC1cMeXg5_D2EY5e9gosnxKE/edit?pli=1&gid=0#gid=0)

Outlier analysis:

1. Some metros are very close to other ones, which can skew the numbers. e.g. San Francisco/San Jose and Riverside/LA. The plot makes SF and Riverside look like outliers but really they are not. 2. Some metros with more teams than predicted are industrial cities that used to be bigger (e.g. Cleveland, Buffalo) 3. Others have teams for likely historical reasons that I can't explain (NO, Green Bay) even though their populations wouldn't indicate it 4. Austin is the largest metro with no teams. 18 different smaller metros have teams. It is kinda close to San Antonio so maybe? 5. San Diego is another outlier. It has 1 team despite being the same size as Tampa and Denver (3 and 4, respectively)
