As a native New Yorker, I am quite happy that the Giants won. While I was always more of a Jets fan, the Jets and Giants fans do not have anything close to the depth of hatred that other rival New York area teams have.
The Mets and Yankees have a sense of history, as most Mets fans were originally Dodger or Giants fans.
The fans of the Islanders and Rangers hate each other with a passion grown out of old playoff losses (I still think Maloney’s stick was high, though it came out alright in the end) and chants of 1940 and 1983.
The Jets and Giants do not have quite that history. They only play each other occasionally. And neither team has been in a position to deprive the other of glory.
So this Jets fan says "Let's Go Giants!" and good job!
