1975 Worlds:Dianne De Leeuw, Dorothy Hamill, and Christine Errath
Dianne de Leeuw in 1975
It wasn't as impressive to me as it's supposed to. It may have to do with the warped screen of the clip, but with consideration of it, Leeuw's speed still appears much in need.
And based on my knowledge of her skating, I am not really convinced of her winning here. But of course, it's just my guess since no clip for Hamill's or for Leeuw's seems available.
Here Dianne performed very safely, but I don't see anything beyond her usual ability, not to mention each of her element appears just so so. In other words she gets by.
What significantly lacks in her skating are speed, momentum, and execution skills, which a skater cannot afford to compete without.
Dorothy Hamill in 1975
This is not Hamill's Worlds performance.
I couldn't find any thing of her 1975 Worlds. So I put up a clip from her 1975 National. Of course, as I expected, she didn't show much difference from her usual capacity as a skater.
Though she may be a bit less polished here, Hamill's skating is still an unparalleled gem.
In the 1975 Worlds, Hamill ranked 6th in short program while she placed first in free according to the record. So we can reasonably guess that she might have fallen.
But it is still difficult to imagine how Hamill ended up in 6th even if she had fallen once. If she had indeed fallen, perhaps twice or more, and others had done superb performances, then it could explain that away.
In other words, if Hamill had performed in the Worlds just as she more or less did in national, she shouldn't have been deprived of her claim for the competition. Simply Hamill's skating is full of unbeatable assets others only can dream about.
Christine Errath in 1974
Again I don't see anything particularly beyond Errath's usual capability.
But this is not her 1975 Worlds performance. So there is no way for me to know for sure how she did in the 1975 Worlds.
Suffice is it to say that the judges at the time considered Errath as one of a leading trio with Dorothy Hamill, Dianne de Leeuw.
All we can tell by comparing Errath and Leeuw to Hamill is that Hamill was the one and only skater whose skating was all rounded and complete.
