I'm really not looking to go down the rabbit hole of this debate, but I always am confused as to why when this discussion comes up people are oddly willing to use Sid's injury to give him more credit. "Well he would have X,Y, and Z had he not gotten hurt..." Which leaves me begging the question, what do you people think causes other players to decline and why is Sid's legacy given a pass for that? Guys aren't given asterisk on their stats that say "*played season with sprained MCL" so I don't really get why Sid is given the "and imagine how much even better he'd be if he hadn't gotten hurt" treatment. Injuries are a part of legacy, is it fair? No, but if a guy bounces from the NHL after 3 great seasons because he had a career ending injury he doesn't get the "we're putting him in the HOF because imagine if he didn't get hurt" treatment, but weirdly people like to cosign that sort of thinking to Sid's legacy.
Sid is a great enough player where his stats stand on their own merit, his injury history shouldn't be used to bolster his story. It's a part of his overall legacy and yes, unfortunately, when you stack him against other players of the same caliber it is potentially a drawback to him, but that's hockey.
