Then I agree there are another ~ twenty guys who could round out the top ten depending on your preference. Breaking down that next tier is really tough, but I think it's fair to say most people wouldn't have more than a few more who they strongly feel are discernibly greater than Chopper (ie. you don't necessarily have to call him top ten, but I don't think you can list ten who are definitely better) .
Put another way, if we were doing a schoolyard pick'em to make the two greatest fantasy teams ever, I think MacInnis ends up on one of the teams (ie. top 12) nine times out of ten.
I think Iggy is similar among wingers: Howe, Richard, Bossy, Jagr, Hull, Hull, and Ovy, but then it's really hard to differentiate among the next tier. I put Iginla near the top of that next tier based on his
adjusted goal total, but I think there's plenty of room for debate.
To the other point about the Flames Cup - Lanny had 1G, 4P in 14 GP in the playoffs (tying him for 14th in team points)...he missed games 3, 4, and 5, though his goal did come in the clinching 6th game. He was huge in '86, though.
