Not ranking them, just sharing my memories of some of the legends being mentioned:
Bobby Hull: The first game I ever went to was at the Montreal Forum in the late 60s, with the Hawks as the visitors. Hull was an absolute bull, probably the strongest guy on the ice, with a combination of speed and strength that was beyond anyone in the league. Unmatched physical presence. And what a friggin' slapshot!
Bobby Orr: I was too young to appreciate the intelligence of his game, but I remember watching his unbelievable rushes and puck control on TV. Also remember Larry Robinson laying a massive hip check on Orr when I was at the Forum.
Jean Beliveau: Saw him at the tail-end of his career, so I didn't see the speed and dominance in his prime. But he was always the team's icon, its face and undisputed leader. Everybody loved the guy then, as they do now. Met him in person about 15 years ago - gave me a nice smile and was as gracious as you'd imagine he'd be.
Guy Lafleur: My first poster in my bedroom was Lafleur as a rookie, wearing a temporary number on his uniform. I was lucky enough to see him through his career, taking the bus downtown to the Forum dozens of times. $7 bought us standing-room tickets that were always available, letting me and my friends hang out in the upper corridors and watch the 70s Habs make history. Lafleur was fast, lithe and deadly, with that flowing hair that - like Hull - made him visually appealing.
I've seen him at a few functions over the years. Weird that this towering hockey icon is about my height.
