There are actually going to be some good pitchers on the FA market this year... if there was time to go out and get one, 2018 would be it... Whether the Pohlads will, who knows.
I'm wondering if this is the result of Neil Allen's paper on fastball command, where Stewart is being asked to do a bit more than throw, but locate that pitch... I hope that's all it is. Otherwise, I think you're right...
