I don't see the same type future rookie value level, but there's chances of surprises. For example, Betts was drafted 172nd in 2011 and only reached number 10 in the soxprospects rankings by the fall of 2013. I doubt we have someone like Betts hiding in the system, but who knows. We've become accustomed to not believing in any of our starting pitcher prospects after dud after dud.
Here's my look at possible prospect arrival times...
2018: Devers, Travis, Beeks
2019: Chavis, Ockimey, Shawaryn, D Hernandez, Chatham, Thompson
2020: Groome, Houck, Brannen, Scherff
2021-2022: Mata, D Diaz
