Start the season out with him in the bullpen.
They can monitor his innings with him that way, work with him at the MLB level refining anything with his pitches that they need to, including his new ones (especially those...)
There are lots of missed games due to weather early on... it would be easy to use a 4-man rotation and then swing guys/ starters as needed (Maeda, Cobb, Mize, Brieske, Holton... all guys who could be both long guys as well as swing starters...).
After a month or so... they can start to stretch Jobe out and then slot him into the rotation when they are ready.
They can do the same thing at the end of the season, only in reverse... if they need to keep him to an innings limit.
Just my 2 cents.
