Snark aside, I feel like you're missing the nuance of this discussion.
We absolutely don't own a comp pick we haven't been awarded yet, even though we tried to get away with it. An original pick that's involved in a conditional trade is still owned by us until it isn't.
We've made or at least I've seen trades made in the past something like a 4th round pick that could conditionally become a 3rd, 2nd, or even 1st based on how the player performs. Are you saying that team can't trade any of those picks moving forward? Ultimately, they traded 1 pick not 4 picks so I kind of doubt that's the case. You can't change the terms of the original trade but it's reasonable to believe you could change the terms of a subsequent trade to work around the terms of that original trade.
