Funnily, I don't remember
@aftershocks (or anyone else) saying they should replace D/F
before worlds. Saying so now with the benefit of hindsight is completely disingenuous.
In your opinion, to which you are entitled. However, first of all, I didn't say here in hindsight that I thought immediately after Nationals D/F should be replaced for Worlds. I said that I was worried about how Haven was actually doing physically and whether or not she would be able to compete effectively since she clearly was having trouble landing her jumps, and it was affecting their confidence as a team. After Nationals, I tried to put aside my worries and hope for the best. There was so much going on about Gracie, and fans understandably pitching a fit over U.S. fed's team selection decisions. So there was a lot to digest, and enough fodder to post about.
Like everyone who is a true fan of U.S. pairs teams I wanted to believe that D/F would be okay. But I did have some niggling doubts simply because both teams were questionable physically. And I never truly believed that Chris was going to magically suddenly be able to land his sbs jumps perfectly.

Just because I say that now and not then does not mean I'm being disingenuous. I did not want to jinx our teams, but I was worried, especially after 4CCs.
It was in hindsight here in this thread that I offered possible solutions, one of them being U.S. fed sitting down to talk straightforwardly with the athletes and their coaches and getting feedback from everyone. I also suggested the viability of not sending Haven/Brandon to 4CCs in order for her physical fitness to be fully assessed. And I wondered aloud about how C/T or C/L might have fared at Worlds, and clearly that would have been another throwing of the dice since C/T have not shown any consistency on their jumping passes, and C/L are a new team without a lot of major competitive experience under their belts.
But let's be honest, Alexa/Chris have never shown consistency on their sbs jumps either, even though they haven't looked quite as bad as C/T in that aspect. In their favor, Alexa/Chris do have other competitive strengths and are favored by U.S. fed in addition to being well regarded by international judges. The problem is about how strong they could be coming back from Alexa's two surgeries. Add to that the question of Haven's fitness.
Clearly U.S. fed was in a difficult situation through some bad luck with newly formed teams still developing and top veteran teams suffering from illness and injury. Plus the fact U.S. fed had let things slide along for far too long doing absolutely nothing to stem the tide of constant partner switching, and the areas of ongoing weakness among most of their pairs teams. Ad they still did not adequately assess the difficulties of the World team selection process and openly try to determine possible alternatives way way ahead of time, instead of at the last minute rushing Cain/LeDuc to Helsinki as an emergency sub, apparently for the wrong team.

Furthermore, I've posted a lot on FSU since U.S. Nationals and I may even have made some reference to my reservations about Haven/Brandon. But even if I didn't voice how I was feeling publicly on FSU, I defy you to tell me that I am being disingenuous because everything must be posted on FSU beforehand, or everything said after an event with the benefit of hindsight is disingenuous.

There's a lot I have been thinking about and not sharing publicly. And I'll bet that's true for all the teams and U.S. fed as well. Everyone was likely hoping for the best and making assumptions that surely these two teams could hold onto two spots. Even a lot of fans on FSU were claiming the Australians would probably not make the cut. I actually always thought they would. But I did not take the North Korean team into account. Still, it is up to U.S. fed to do a better job. But it's not a surprise that they don't. And this isn't the first time, nor likely will it be the last that they go about things in a way that simply does not help their athletes in either the short term or the long term.
All the smart asses on here who enjoy pushing back can feel the way you feel and say what you will, instead of making any attempt to be thoughtful and reflective. I appreciate everyone who is seriously having a conversation here and offering something of value. The rest of you can go ahead and continue trying to distract and hijack the thread. I'm personally not that easily intimidated by other posters trying to tell me what to think, how to feel, and how to behave.
