best Yankees and my favorite Yankees.)
I considered other leagues (MLS, WNBA, etc.) but none had teams with a serious enough track record. I also thought about Manchester United, which I heard was the winningest soccer franchise, but then I learned that Real Madrid has way more wins than Man U, and I couldn't find really good records for either, so I limited the list to American sports. Anyway, add teams I missed in the comments, and check us out on Facebook, where you can "like" us for a chance to win nothing!
