Well with JV we knew our competitive window was closing and a rebuild would be imminent. JV also had some injury issues and had a year or two of declined performance (by his standards). Even at the time I was underwhelmed with the return. None of it was major league ready.
With Skubal, this is a guy who is young, cost controlled for years, still improving, and we are (hopefully) at the beginning part of a competitive window. So the value of Skubal to us and the stakes of not getting a gigantic return for him are especially high.
