There have been franchise-altering trades in New York sports, have there ever. The Rangers just traded for Patrick Kane, the way they traded for Mark Messier once, before Messier came here and became one of the transformative players in the history of New York sports. A hundred or so years ago the Knicks traded for Dave DeBusschere and that trade, by the great Eddie Donovan, ultimately changed everything with the old Knicks before their first championship.
