With a 100 win team, a rebuilt bottom of the farm system and a pro scouting group that has mostly done a good job of finding low cost bench players in low asset trades and signings (Merrifield being an exception, but one year deal) I think Phillies are more interest in gambling on future starters than safer back of the roster types.
Think they see minor league free agents in the 24-27 year group as the way to build ML ready organizational depth. Sign them for Lehigh (and 30+ veteran RPs, hoping for another Hoffman).
So they really don't care if they miss on most of their top 10 draft picks if they can hit on a RP good enough to be a 7th+ inning guy, back of the roster starter, or a pushing to start position player. Which means gambling on big arms, players who slip due to injury or weaker competition or other reasons that push down a player with raw talent.
When you're picking 25th or later most years, those "sure things" are long gone.
