Why does the Index treat Brooklyn and Nassau County as separate from New York City?  The Index relies on the concept of identity. Brooklyn and Long Island have distinct identities within the megalopolis that is New York City. Anaheim is treated separately from Los Angeles for the same reason.

Shouldn't where a team plays its games define its identity?  No. The Packers played games in Milwaukee, but they have always been Green Bay's team. The Jets and Giants play in New Jersey, but unlike the Nets and the Devils, they belong to New York. The location of a stadium does not determine a team's identity.

Why isn't soccer included in the Index?  This is an index of major professional sports. Including soccer puts us on a slippery slope that leads to roller derby and competitive eating.

Have you ever thought about extending the Index to include college sports?  Yes, many times. And each time it was accompanied by the recollection that I have a job. Perhaps in my retirement!

Any chance of adding a sort for total city championships for each division?  Done. There is now a sorting options link on the home page. I'd also like to do one for total city regular season winning percentages one day as well.

What about the USFL?  I loved that league...Jim Mora and the Phillie Stars. But unlike the ABA, WHA, and AAFC, it died a quiet death with no legacy of surviving teams, so I had to draw a line.
