He's already been mentioned in this thread, but for me, no good-not-great player has ever had a quicker escape hatch from my brain than Cory Stillman, despite his career coinciding directly with the 2 decades in my life that I am biologically predisposed to remembering best.
He first showed up on the radar full-time in 1995-96, and got no Calder votes in a sort of weak-ish year where plenty of other guys with similar numbers got fringe support. I remember becoming aware of him as a middle-of-the-lineup forward around this time, and probably assumed he was a contemporary of someone like Nelson Emerson or John Cullen, not a guy like Bertuzzi or Sykora who would show up in the sort of "future watch" hype pieces in magazines.
Then he logged six more seasons in Calgary, without ever getting any kind of "Mr. Flame" reputation than I'm aware of. Then he was there in St. Louis in some pretty strong years, of which I remember Pronger and MacInnis, the Slovaks, Tkachuk and Weight as ringers, Turek and Johnson trying to hold onto the starting job, the variety of defensemen left to fill the rest of the game (Khavanov, Reirden, etc.) and even guys like Mayers and Nash, but not the guy who finished 6th and 3rd in scoring on those teams.
Then he goes out and wins 2 cups in a row and I can't remember what his role on either of them was. Secondary scoring I suppose? Both Recchi and Weight seem more like Canes to me, despite Stillman finishing 3rd, 8th (injuries I guess) and 6th (traded) in 3 seasons for them.
I refuse to believe this guy played for Ottawa or Florida, despite evidence to the contrary.
