Sidorov's skating might be his biggest hindrance. We have a player similar to Sidorov in Pastujov, but Pastujov is a year ahead of Sidorov. If we're not talking about Pastujov into that block of prospects, then we shouldn't have Sidorov in that group either.
Dionicio also has skating issues. From
THW on late round gems in the 2023 draft:
The biggest knock to his game is his skating ability. He struggles with his agility, speed, and quickness.
Dionicio is likely to be available late on Day 2 of the draft. He is unranked on many public lists and on the ones he is ranked on, he ranges from 90-172. If a team can grab him late, with the proper development, he could be an exciting addition to any prospect pool.
Maybe Dionicio going across the pond and playing on a larger sheet of ice could help improve his skating because the lack of if could be exposed often on a bigger playing field.
