1. Wayne Gretzky.
2. Ray Bourque.
3. Brian Leetch.
4. Daniel Alfredsson.
5. Erik Karlsson.
My older brother was a big Gretzky fan so I didn't really have a choice.
When Gretzky was traded, he switched to the Flames in anger, and I took a little while to settle on my next favourite team, the Rangers. For some reason, I liked Kisio, Greschner and a young Brian Leetch. It was sort of the hinterland of fandom in Ottawa at the time until Messier was traded there.
In the interim, I had always liked Ray Bourque.
My Rangers fandom persisted well into adulthood, until I started buying tickets and seeing the Senators on my own (~early 2000s) at which point the hometown team won me over.
If I had to choose one, it would be Daniel Alfredsson, with Brian Leetch a close second.
