WIthout giving it too much thought, off the top of my head this is roughly my tiering:
Tier 1/Mount Rushmore: Boucher, Bathgate, Leetch, Lundqvist
Tier 2: Bill Cook, Johnson, Gilbert, Park, Giacomin, Ratelle, Messier, Richter
Tier 3: Bun Cook, Seibert, Hextall, Worsley, Howell, Vanbiesbrouck, Graves, Jagr, Panarin, Fox, Shesterkin, etc.
Tier 4: Kerr, Laprade, Dillon, Hadfield, Greschner, Gretzky, McDonagh, Kreider, etc.
I'm sure I'm missing half a dozen players in each of tier 3 and 4, but that's the rough idea. I think Kreider can easily jump into tier 3 (if he isn't already there), which puts him in the top 20-ish conversation for sure.
