This always happens after an Olympics - reactive splits (or teams staying together that shouldn't have) based on the results. When teams that had been together a long time won (V/M, P/C), long-standing teams stuck it out. FB/C's win threw that conventional wisdom out of the window.
What these younger teams might not realize, however, is how instrumental it was that a) C was the reigning OGM and has that pedigree, and b) the French fed is willing to get its hands dirty, always.
We've seen this in the pairs as well post Aliona and Bruno, but there have also been partnerships and unretirements that flopped horrifically, so it really is a toss-up. We just won't know if it was the right call until we see the new pairings. But I think ice dance in particular has a bigger problem in that it's been rotting from within for the last quad+ and even if you reshuffle the teams, it no longer makes any sense as a sport.
Ultimately, it's also an extremely expensive endeavor and it's inevitable that some skaters and feds will simply be priced out of it, with things being what they are in the world.
I mean, I agree that there are usually splits and retirements post-Olympics, but having been here since post the Sochi Olympics in 2014, I feel comfortable saying that this is out of the norm.
Especially for Canadian ice dance, the majority of the teams that split were the ones that were about to get a real push from the federation. L/L were going to be the undisputed #1 with a push on the world stage for that, F/A were likely to be #2 (assuming L/LG would have retired like we all expected) or at worst #3 for this quad with many more opportunities. Even H/L would have moved up, most likely. So for all of them to implode like they did? Wild.
Plus, most of the time the splits were about one skater deciding to retire from competition and the other wanting to continue, and now we have numerous teams that split, but they all want to continue, and none of them have a new potential partner that is more promising than the partnership they broke. So yeah, WILD.
