Okay, so I'm going to help you out a bit with this. You're not going to listen, because you don't, but I'm going to do it anyway.
This....is a draft slot value chart:
Each NHL team has their own, but they're all more or less identical to the point where some teams have published theirs because no one cares if anyone else knows how they value a pick.
So, a "2nd" that is say, 45th overall is worth 75 points. A 3rd is worth ~20 points. You're not getting someone to give up an asset (a 1st) worth 140-180 points (a late 1st) for Carlo (2nd = ~75 points) and Maccelli (3rd & 5th = ~28 points).
