Concerning Carlsson, maybe moving up could be a realistic option to get him assuming a team in the top 3 really likes Michkov and knows he will surely fall to 5 (imo CHI). Lets say this is the draft order :
1. ANA : Bedard
2. CLB : Fantilli
3. CHI :
4. SJ :
5. MTL :
As I see it, SJ would surely take Carlsson if hes there at 4th, but they might be scared of Michkov especially with a guy like Smith available. So, lets say CHI knows that and also wants to add more picks, maybe they call KH knowing he surely loves Carlsson and asks him for the 5th OA and 37th OA. That way, CHI could get the guy they're taking anyway + a high second, and MTL secures a superb player in Carlsson (who's imo is much better than Smith).
