That's the thing about Edrian, the timing on switch coaches while he was young to address the issues and as I backtrack his previous performances which I noticed that he has already hit the ceiling with Beland and sticking with him for so long can have setbacks. But don't worry, just like Anna Shcherbakova which she was used as an example of not to follow her technique that Edrian will be used as an example if skaters don't change coaches when need as it hits the ceiling.
Edrian will be remembered for his skating style. In retrospect, if Edrian made a mistake it is to switch for the PH right before Covid. With the very lengthy lockdowns in Quebec, he was simply not able to train. But who could have seen that coming ? And of course, we know why he wanted to do that... Only very few elite nationally were able to get very limited ice time when things started slowly again. As a PH skater, Edrian didn't belong to that group. So if you want to find an explanation for his "ceiling" you have it there.
I personally don't think he was ever going to be Nathan Chen and I have always enjoyed his skating no matter what. it's not always about the results... If it were, the entire crew of Canadian men could just retire right now because none of them will win a world medal... as a matter of fact, only one of them will go to Worlds. So are you saying that Roman, Gogo, Aleksa, Wesley and others should quit because they cannot compete with the top skaters ?
One last time, for Canadian skaters, there is an immense pride in competing for Nationals. Maybe that's something that is more remote to your perspective since you root for small feds skaters. I am pretty sure that Edrian is motivated by skating at home, in front of his family and friends, but that's just my opinion... Yes, I have explained it before : Worlds were going to be in 2020, and Edrian was training hard to improve his content in what you called the fluff piece... It's not a fluff piece, it's an actual competition. Not only worlds in Montreal were canceled but he lost his jumps during lockdown. Many skaters never came back to the same level... not just him.
I admire his courage to keep going and recuperating most of his content, 4 years after the initial objective... and I am pretty sure that this is his last season, with the objective of simply competing at Nationals.
Seriously, at this point, I think it's best to just wait and see... unless you really have a crystal ball. I certainly don't have one.
