Yup. Holliday is an everyday position player that just made his debut. Skubal is a power pitcher with injuries on his resume and only under control for 2 seasons / 3 postseasons. There's an argument that the quality of the players which tips in Skubal's favor but its offset by the remainder of controlled years.
Now, I don't want him dealt necessarily. However, if Holliday is included as the main cog going back, then maybe other teams decide they really, really like Skubal and up the ante. Maybe that occurs in the offseason. Baltimore doesn't get the ring this postseason, Burnes leaves, and Skubal can backfill as that ace at the top of the rotation. And then the bacchanal of trade offers can go from there.
