As a Devils fan who was partial to both the mid-80s Flames and Blues teams (even own a Rick Wamsley jersey for some reason) when our team was terrible and I needed someone to root for during the playoffs....
Dougie Gilmour was a favorite of mine, and almost the prototypical two-way gritty center with skill. I'll agree with alot of previous posters that I think he may have actually been better in Calgary than in a Leafs uniform - and his early career is underrated... The point that 'he got a bigger role on the Leafs and ran with it' is spot on for me -
This has got me thinking what an interesting phenomenon it is: that distinctive feeling you get as a fan when a certain player steps on the ice. "presence"
I mean - Gretzky/Lemieux etc obviously had it - and when you judge Top100 all-time, it is worthy to note that Gilmour certainly had it in abundance and especially with the Flames.
Some of the others mentioned as comparables (LaFontaine, Brind'amour) maybe didn't engender quite that same feeling.
Just my opinion - and a completely non-stats-based take.
