That's my point, we really don't know how players will develop until they have 2-3 full seasons.
If Hernandez continues to hit like he has since he was made the leadoff man, well, you don't dump 4-5 WAR players in their peak seasons.
If Rupp and Joseph can learn how to hit, they certainly have the power to be solid starters, and Joseph is showing some fielding chops (great arm at 1B).
If Galvis continues to build on the last couple months of last season and April, why would you think of getting rid of a top fielding SS who can give you a .150-.200 ISO at the bottom of the batting order?
To me, these issues are resolved on the field - when you get to the point that you have a surplus of talent then you make some moves, but not a "projected" surplus.
It's really early, maybe Cozens makes adjustments, maybe the light goes on for Crawford, maybe the guys I mentioned above have a great summer, or maybe a few flop.
And of course, you never know when another GM will make Klentak "an offer he can't refuse."
