IMO once Skate Canada decided to send Kevin to Sportland Trophy, Liam stopped being an option for them. I'm guessing they entered Kevin to ST in the hope he would get the minimum score for Worlds and not because Kevin was dying to win the ST title and they wanted to humor him. lol The closing day for entries to Sportland Trophy was
Feb 20, that is one day after the men's short program at the 4CC and one day before the men's free skate at the same competition. Looks like SC trusted Kevin more in spite of his four falls in the short program at 4CC.
Liam did tweet on
Feb 23 "
New boots! Thanks @JacksonUltima @MisirRaj can't wait to get training for worlds in these!" but I suspect he was not aware yet of their decision. Unless he meant 2017 Worlds. I strongly doubt it though. Yeah, it's just a theory but it's not totally baseless, I think.
The only reason I mentioned Slipchuk was that he is the only one Skate Canada official I know. Never got bad vibes from Slipchuk myself but I live on the other side of the Atlantic and vibes might not be travelling long distances. lol
