MLB - New York Mets (from NY/NJ area)
NFL - New York Jets (from NY/NJ area)
NBA - New York Knicks (used to be the New Jersey Nets, but the move to Brooklyn killed my fandom for them)
NHL - New York Islanders (didn't get into hockey until after I left Jersey for Long Island; Devils are still my second team)
MLS - Atlanta United FC (can't get behind either NYC club, the Red Bulls because of the corporate name and NYCFC for being the bastard child of Man City and the Yankees)
CFL - Hamilton Tiger-Cats (I would really, really like to move to Hamilton at some point)
EPL - Stoke City (I... honestly don't know why)
NCAA - Syracuse Orange and Coastal Carolina Chanticleers (Syracuse are sort of the default NY college team, and I prefer CCU over SCar or Clemson because... teal)
AHL - Bridgeport Sound Tigers (Islanders affiliate)
ECHL - South Carolina Stingrays (literally play in the city I live in right now)
AAA - Albuquerque Isotopes (love the Simpsons reference)
AA - Trenton Thunder (Jersey)
