Seriously no one thinsk less of Orr because he slot 2 of thsoe 3 Harts to clarke, nor should they.
Likewise Crosby has 2 Hart and 2 other seasons were he was fully worthy of the Hart as well but lost very close races due to circumstances (much like how Clarke won 2 Harts due to circumstances not necessarily being better than Orr).
Mikita has the best resume of the 3 guys listed above (both overall and up to age 27) and both Trottier and Clarke add very little after 27, compared to the level Crosby is playing at right now and presumably can carry for another season or 2 if not more one would think.
I don't have the time right now but when I can I will go over each players case more in depth.
Crosby already has 4 seasons where he has finished top-3 in Hart voting. Had he won over Ovechkin in lockout year, nobody would have batted an eye.
His rookie season, Crosby didn't really register in Hart voting. He was 24th with 2 fifth place votes. But he did manage to pull out one of the best rookie seasons in the history. Since expansion, here are the players who have finished top-10 or higher in points in their first year. I'll add the age in too to give some perspective.
Gretzky: Tied for 1st. 19 year old.
Selanne: Tied for 5th. 22 years old.
Peter Stastny: 6th. 24 years old.
Ovechkin: 3rd. 20 years old.
Crosby: 6th. 18 years old.
Bossy: 6th. 21 years old.
That's impressive company and while it might not be high on all-time great seasons. It definitely gives him a head start on most players.
His sophomore season, as everyone knows, Crosby continued his business as usual. He won the scoring race and was voted as the MVP with big margin over Luongo and Brodeur. The next skater in Hart voting was Lecavalier with 5 1st place votes compared to Crosby's 91. I don't think anyone disputes that he was the best player on planet that season. It wasn't exactly an all-time great season in the context of best ever. But it certainly keeps him in the running with all other players than Gretzky.
Third season, Crosby had his ankle injured when he was leading the league in scoring. Now, of course injuries need to matter. But I don't think they should nullify the season in all. Even without injuries I am certain that Ovechkin is the top-dog that season. But 2nd in Hart voting was Malkin who was considerably behind Ovechkin. Crosby was playing bit better than Malkin that season and he deserves some credit for it. So, how much value should that regular season hold for Crosby? In my mind, it proves that he was still one of the top-2/3 players in the league. His play was at level that would have given him serious Hart consideration without injuries.
Fourth season, Crosby finishes 6th in Hart voting and this is probably the only season where he clearly lost on game-by-game basis to his team-mate Malkin. Probably his "worst season" in the sense that had he never been injured his projection would have been higher in every season. Still a good season tough.
Fifth season, Crosby finishes third in Hart voting. I have no problem for Henrik winning the coveted trophy. If there could have been another player taking it, it would have been Ovechkin. Not Crosby. But there is no doubt that Crosby was third best skater that season. He finished with 729 points in Hart voting against the next highest skater, Stamkos, who had 28 points. No contest. A really good season, but not one for the ages.
Sixth season, Crosby kicks it up a notch. He is playing the best hockey of his career and frankly, nobody else is close. He gets injured, but everyone and their mother knows who was the
BEST player that year. That season certainly doesn't lift Crosby to the immortal level. It could have, but the injuries got in the way. But people can't treat that season like Crosby was playing the same level as other 66 point scorers. No, Sid was the best player that season.
Seventh season. This is the only season where I see little to no value on all-time level. Would Crosby have been contending for the top-spot without injuries? Most likely. But the sample size is just so small. But it does give us some information. In the games he played, he was as consistent producer as he has always been. Right on leagues top. So, even if that season doesn't add much it certainly does not imply that Crosby could have not been on top level.
Season eight. Again, injury problems. But finishing practically tied for the Hart trophy with Ovechkin and winning the Lindsay is a solid proof that Crosby was the best player on planet that year.
Ninth season. First full season for a long time. Crosby doesn't disappoint. He doesn't manage to tear up the competition as some predicted. But he still manages to prove that when playing all games, there is not many, if any capable of challenging him.
Now, I get that injuries bring down the overall value of his career. But how many players are there who have been playing (when playing) at least on top-3 player level 8 seasons out of first 9? And the one where he is not on top-3 there is a good argument that he is top-10. (Rookie season)
The more I think about it the more it feels like Crosby is going to be ranked really really high in few seasons. We all expect him to dominate the scoring race this season again. If that happens, (fingers crossed) is there really more than 5 guys in the history with better consistency on top-level for first 10 seasons?
