Is the Nationals Trying to Do Something Different With Kvallie Gray?

Josiah Gray has not performed up to expectations thus far but seems to have quite a hit up so what if anything are they trying to do differently with Gray. Kvallie Gray is sort of the other youngish standard bear in that rotation who has a lot of high hopes resting on his shoulders. And I would see some results and seeing some more consistent results as he'll be tinkering with his whole career, whether it's pitch usage or base repertoire.
