Interesting NHL Trivia Question

This is something I came across last night while looking up some things on Hockey Reference. And I think it makes a really good trivia question, so here we are.

Disclaimer: This is a no win situation. If you get it wrong, you get it wrong. If you get it right, you will be accused of being a cheater and judged. Cause I probably would not have guessed this if I had fiddy tries. So here we go:

Of the 10 players who played in the most playoff games in NHL history, 9 of them are Hall of Famers. One is not. Who is he?

Note: This is not like a future Hall of Famer, like a Jaromir Jagr or something like that. So it's not a trick question. This guy played his whole career and will not be making it into the Hall of Fame outside of visiting.
