I expect this level of lunacy from NBA fans, not hockey fans.
This list could easily be 4 Yankees, especially given baseball's dominance of the US sports landscape until the 60s. Ruth, Gehrig, Joe D, Mickey, and Yogi were larger than life idols.
Obviously, LT should be there. There was a time when football began to assert its dominance that the likes of Gifford and Huff owned NY.
Few realize how enormously popular the Rangers were from their inception until WW2, regularly drawing SRO crowds to MSG while MLB and the NFL struggled during the Depression. Frank Boucher and Bill Cook were matinee idols.
The Knicks were in a decade-long funk before Reed and Frazier helped revitalize them.
Hate to say it, but what about the Islanders? They were a machine during their dynasty - Potvin, Bossy, Trottier.
And we can't forget the most talented Knick to pull on the shirt - Brooklyn-bred Bernard King.
NY once had 3 baseball teams. What about Mays and Jackie, among others?
I would be hard-pressed to pick 4 from so many choices.
