Katia won Battle of the Blades with 3 different partners, I think. Or came 2nd with the third. She's that good.
In an interview last year, Sergei Voronov said that in order to help coach T/M, he researched pairs. About G&G, he said (not a direct quote but close): About unison: Sergei Grinkov took skating in unison to new highs. It made even the simplest moves they did seem like magic.
I agree with Voronov that it seemed that Sergei followed Katia. But I'm not minimizing what he did. Besides the exquisite unison (not that easy!), he also was very graceful with lifting and throwing. He was the more consistent one with jumping till oly 1994.
Back to Topic! I'm not sure whether this is an Unpopular Opinion ... yes, on the whole I think it's a Minority Opinion:
Mishkutenov and Dmitriev were better at the Lillehammer Olympics. No mistakes ... but also, they skated with passion, and to win.
(still, I saw a pretty convincing youtube analysis of the two skates once, using IPS -- it came away with G&G the clear winner, too)
