I was always a big Forsberg fan when he was playing in Colorado so I would have to say him. I also always wanted Brodeur to play for the Rangers, not just because he is an outstanding goalie but also so the Rangers didnt have to play against him lol. Out of the newer guys to come into the NHL I would have to say that I would LOVE to see Ovechkin in a Rangers sweater, but that would probably only happen if he is 45 years old and skating with only one leg, then he would be ideal for our team...
Ditto, largely for the same reason! Watching him play this season is a real pleasure, whether you were a fan before or not, though.
Plus Saku Koivu, because he was a star for TPS before playing for my second favourite NHL team.
Honourable mention goes to Joe Sakic, JR (I know lots of people hate him, but I loved his combination of skill and desire), Forsberg and Brenden Morrow. I should also add Jari Kurri, because his days on the Rangers shouldn't count.
