I'd think more like:
Stud: Arrieta - Stroman
Solid guy: Tillman - Norris (ugh that's painful to write)
Relief ace: Britton - Hoffman/Osuna/Castro
Relief guy: Matusz - Sanchez(/Reid Foley?)
I'd exclude Hutch from this, he's got a nice, semi-large dataset from which to judge that can assume he's already a solid guy. Of course, some of these guys will succumb to injuries, which I won't try and project, but if I had to, Hutch would certainly be most likely after TJS and then the velocity things last year.
