Yup. It's extremely hard to formulate truly accurate opinions on any of the DSL (or ACL, for that matter) pitchers. I am still only half a season or so removed from the LHP Osbriel Mogollon rise-and-fall within the organization. He was a gem throughout his DSL summer. Came stateside; was promoted to Low-A Carolina; struggled mightily; was sent back to the ACL; played sparingly but still struggled; and was Released.
It's very very much hit or miss and, honestly, mostly miss (tho, that may be changing). We can use any number of stats to try to read the Tea leaves but until we see them face those Low-A bats we really don't know all that much of anything.
This being said, I personally considered the LHP Jesus Flores and RHP's Yorman Galindez, Dikember Sanchez, Brailin Rodriguez, Manuel Rodriguez, and Daniel Corniel collective developments to be toward the top of my favorite system storylines of the entire 2024 season.
