Perhaps for you. I'm not very sure I'd agree. Tarik Skubal is really that good, IMO. And while I think Wicks is a nice arm, and while I think Pete Crow-Armstrong has significant upside, I know Skubal is a really good MLB pitcher (28th in fWAR last two seasons despite time missed, for example, 3rd in xFIP with arms over 190 IP). PCA and Wicks are unlikely to both hit their 90% outcomes. Skubal already has. That's not saying I'm gung-ho on anything, only that the bolded is subjective, not objective.
I also think the last sentence you wrote is highly subjective. We can say that a few ways. "Cubs trade two unproven players for a controllable, 27 year old SP who has the third lowest xFIP over the last two seasons" and make it sound way differently. Both are true, but add in subjective things to make it highly biased. I'm going to avoid saying either, because both are true.
Again, I really haven't thought about it, and I'm not super interested in getting too deep into what if's here, trade packages and tangents. What I know is this: Tarik Skubal is really, really horsefeathers good and any trade that would end up with him would hurt. But you'd also be getting a really good player back and that's what those cost. That was the original point of the post, that the Cubs and the Tigers could find common ground somewhere and why the Tigers would be interested at all, not the minutia of a PCA or Matt Shaw trade or whatever.
