The ideal RP has a 95+ FB and one plus secondary pitch (slider, changeup).
Klentak did focus on college arms the last couple drafts, these are the "low cost" RP guys.
Miller 4th rd
Mayer 5th rd
Schultz 6th rd
Schulze 7th rd
Ragsdale 4th rd, then signed
Antle, Hughes, Sullivan, Woodward
The advantage of college SPs who may be marginal 5th guys is they can rise rapidly if they gain velo when they move into a RP role.
2018 they didn't draft many RP arms
2017, Brogdon 10th rd senior (so much for "throwaway picks"), Warren 14th, Dohy 16th, Jones 18th
2016, Romero 4th,
