Neatoooooooooo! An all-time goalie thread.
Cool observation, and in many ways true. But I think they'd match up more like this talent/skill wise:
Hasek-Hall - The dominant type who would win games for their teams, because they had to. Buffalo and Chicago weren't exactly powerhouses of their day and each only have 1 Cup ring because of it. Hasek cleaned up on the Vezinas where Hall kept getting named first team all-star, which is equivalent seeing as the Vezina was the lowest GAA back then. Both broke away from their peers to create their own style regarding stopping the puck. While many acknowledge Hall's contributions to the game by inventing the butterfly, Hasek really impacted the position as well, just not as directly. Maybe the best goalies of their generation but get overlooked because of Cup wins. Durablity is really a huge difference here, but as a talent analysis I'd say they're similiar.
Roy-Sawchuk - Both winners, both clutch. 1-2 in all-time wins. They are both generally considered the 'best' of their era because of their ability to win. They both seem to have an extra gear that they can turn on where they are unbeatable. Roy I know this because I've seen it, and Sawchuk based solely on shutouts and reading about his brillance.
Broduer-Plante- Both winners, not in the sense they stole game but made the right saves at the right time while playing behind some very good teams. Plante and Brodeur both really played the puck remarkably in their respective eras and really had a huge impact on the team that they were on becasue of this. Plante won Vezinas and Brodeur won Jennings trophies. Not too many goals were scored on these guys.
