Sorry, but if this was your takeaway, you missed the point.
Drouin wasn't traded the moment he was walking away from the team. If they had done so, they would have gotten a significantly worse return. Instead, they reconciled, had him put up a 50 point season and THEN traded him for value. Whatever the return is in terms of position is meaningless.
The Rangers are better off having Kravtsov play a full season, put up 40-50 points (ideally) and then trade him for a guy we can actually use, rather than another magic bean on day 2 of the draft.
I don't expect that to happen because as always this org will f*** it up and we will never get anything useful in these scenarios, despite other teams being able to do so. I give Drury 2 years before judging his tenure as a GM, but this is his first big test early on. It's up to him to maximize the return here.
