If his role is to be an offensive Dman with PP1 time, he should be fine as long as his pairing partner takes care of the D stuff. Also a new contract year so he'll be motivated.
As Ouro said, he might be paired with Matt Roy so that could be really beneficial for him. I think the table below highlights his strengths and weaknesses well. That was from the end of February
He creates a lot of offense with his elite shot (5th best goal scoring D-man in the NHL since 2019-20 when he was 21 y/o). Only Makar, Josi, Hamilton and Werenski have a better GPG during the last 5 years. He's not a really good playmaker though. He struggles against heavy forecheck as his decision making is a bit like Ceci and takes a microsecond too much time. He retrieves the puck well but you have to give him a quick exit option or he might struggle and turn it over (which is frankly the case for most D-men except those who excel at transition like Chabot or Karlsson)
I think he'll have a 45+ pts season with more stable defensive play. This trade is most likely going to look like a huge loss for us, unfortunately.
