This would be logical. Lynn is getting a late start, Odorizzi has had health issues, Berrios probably doesn't need to be pushed, and Gibson may not be worth pushing.
I think they can reserve the option to skip someone and that can be a good thing, but if they are using it to justify giving Hughes a chance that his diminished stuff may not warrant, that is a bad thing.
No problem with them skipping or not skipping anyone's starts early in the season ... unless they're skipping Hughes' starts. I'm all in favor of skipping those.
