While the rivalry between the New York Rangers and their long Island upstarts has a long, bitter history, there have been a number of players who have crossed over to play for both teams.
52 former Rangers have skated for both teams. The current edition of the Rangers includes one player who began his career on Long Island. Ryan Strome was a first round draft pick and is now a Ranger, via Edmonton. There are no former Rangers on the Islander roster.
While 52 may seem like a big number, what is really rare are trades between the two teams.
