To be fair I think the Rays' system is quite deep which somewhat explains his low ranking but there's no way he's not at least a 45 FV and appears below someone like Jose De Leon who can't stay on the mound.
Also, it's April 16 and fangraphs is still missing the Blue Jays, the entire AL Central and the entire NL West. I understand that as a mostly one person job with McDaniels joining halfway it's hard, the lists are in-depth and it's free content, but it's a pretty big shitshow that they're just barely above halfway done with no end in sight. At this rate they won't even be done by the draft.
