Right. And if it ends up bad... then its bad.
Good = Good
Bad = Bad
How am I the one considered to have a "hot take" here?
Yours is a hot take because generally it's an unfair way to judge a move. First I'll say that the purpose IMO of judging a decision is deciding whether to follow the same course of action again. If your reasoning for judging moves is different, you may see the merits of a different system but I'll judge the systems based on that goal.
Then there's two systems being proposed here:
1: you judge a move based upon the perceived value of what went in and out at the time of the move, not the actual results which you cannot predict at that time.
2: you judge a move based upon the results sometime later.
Let's analyze these schools of thought with dice. Say that I propose a trade to you, I'll trade one roll on my 20 sided die for 1 roll on your 10 sided die. This seems like a great trade for you, you get an average roll of 10.5 instead of 5.5 and have the potential to do better than is even possible on a 10 sided die. So you take the trade, we roll and you get a 1 on your 20, and I get a 10 on my 10 sided die. Based upon system 2 you would then argue that you made a bad trade. I got the better result than you did.
However if immediately afterwards I offer you the same trade (a 20 sided roll for a 10 sided roll) if you are a follower of system 2 you'll foolishly decide to keep the 10 sided die. A follower of system 1 will recognize that the first time they made the correct decision despite the unlucky result and choose to take the 20 sided dice again.
Now if we consider hockey we have to recognize that you can't use either of these exclusively. You always judge a decision based upon the information you had at that time. However you can judge the information you had based upon the results. For example let's assume Edmonton crazily offers McDavid for Christoffer Ehn. I claim that trading Christopher Ehn for Connor McDavid is a bad idea because I think that Ehn is a better hockey player with more potential. When McDavid has an amazing career and Ehn becomes a journeyman based upon system 1 I may say "I thought Ehn had more potential and thus I made the correct trade. I just got unlucky with the result." However I have to consider that maybe I evaluated them poorly and it wasn't just the case of Ehn minimizing his potential and McDavid maximizing his. Next time I'll still choose to take whoever I think the better player is but hopefully the first trade taught me that players like McDavid are better than players like Ehn. I evaluate the results in this case to judge my ability to rank players. It was obviously tremendously flawed. My trade based upon the information that I had "Ehn is better than McDavid" was still correct. I just had bad info.
So what this chat boils down to is how you value DLR and Fabbri. Personally I'd argue that DLR is like a guaranteed 4 and Fabbri is a 20 sided die. Sure we may roll a 1-3 in which case the guaranteed 4 was better, but I'd still take Fabbri because on average he should be much better than DLR. If DLR scores 50 goals this season, then I'll have to reevaluate the way I judged him. I thought he was a guaranteed 4 but he rolled a 19 so he must have also been at least a 19 sided die. I'd still take the player I judge to be a 20 sided die over the one I consider to be a guaranteed 4 though.
