I think he was in the Euro league, so not likely to accept a PTO.
In fact, it might have had to be an ATO, since he wasn't previously drafted.
The best I can find is he was in the 2020 draft and was passed over. He didn't do a lot in 2021, so not selected if available. Was available to Sweden for the WJC 20 and 21, but didn't make the team.
He may go higher than 6th or may drop to 7th. He's getting press, so lots of teams will know about him. A 21 year old is still a risky pick, even though he seems to be killing it. Do you look for another Wolf or a guy like this. He might be another Dal Colle.
