LIVE, I'd love to have been able to see "The Rocket", Maurice Richard. The most electrifying player of his time, if the stories are true.
I've seen Gretzky and Orr and Lafleur dozens of times on TV, but never in person for some reason. All of them would be included in a list like that.
Glenn Hall-to see the man who invented the "butterfly" style re-introduced by Patty Roy in the 90's.
Terry Sawchuk-to see the greatest goalie ever in person, not on newsreel footage.
Saw Bobby Hull with the Jets, and he was still amazing. To have seen him in the early 1960's would be incredible.
And the "hated" Soviets of the 1970's. For more than 5 or 6 games. They played the game the right way: speed, skating, passing, stickhandling. Too bad they didn't have much passion.
