They were removed because they underperformed.
Call it "underperformance" or whatever - the ISP has specific scores you need to achieve either domestically or internationally and they didn't achieve those scores. It's the same reason the Mokhovs are also not on the ISP at this time. Same with Fitzpatrick/Bearinger and both of those teams made it to Nats.
They were selected for Skaye America only to have it taken away and then ultimately withdraw from the FS of the U.S. Pair Final. They were with WASA that year which initiated the switch to Dalilah because of poor performance.
Are you implying that they were "fired" by Meekins & Mishkuteniok?
I think the only thing that is publicly known about their situation is that Grace was prone to some sort of anxiety/panic attacks either right before or even during some of their programs during the early part of the season last year. There was a verified report of her collapsing at Cup of Colorado (which was after they'd been given the SkAm assignment) and then they were withdrawn. No one has ever given any credible information as to who made the decision regarding the SkAm assignment - and there were several people here in this thread who asserted that the USFS would not "take away" a prestigious assignment like that after it had been publicly announced.
As far as the US Pairs Final - we never did get a good explanation about their withdrawal there - and their SP score wasn't great but it wasn't outside the realm of possibility that a solid FS would have gotten them to Nats - they were less than 1.5 points out of 7th and only about 4.5 points out of 5th.
What is publicly known is that 1) Danny had been coached by Dalilah when he and Nica Digerness were partners, and 2) Grace was coaching in Monument by early December - she shared pics of their holiday show and commented about how proud she was of all her skaters on her IG - the clear implication being that she'd been teaching/coaching in Monument for long enough to have established some sort of connection to those skaters. All of which is a roundabout way of saying maybe the switch happened for practical/economic reasons like only having to make one drive to and from work/training center a day instead of factoring in a commute between Monument and WASA and, for Danny, returning to a coach with whom he had a prior professional relationship.
So, please, feel free to enlighten us if you have other information that contradicts what, to me, appears to be plausible and far less titillating reasons for the coaching change.
What are the options to continue to train if you don't have a coach anymore.... moving to another state is the other option as there are no other pair coaches in CO.
I'm not sure what Grace's educational/professional plans are - Danny has already completed his Masters, so I'd guess they have plenty of options if a) returning to WASA isn't an option, and b) they're open to moving to another state.
