We really didn't turn Crawford into a regular.
The other guys you mentioned: college draftees. We are decent, slightly below average but decent, in drafting/developing college hitters. Where we are historically abysmal are H.S. first round position players. Even with college hitters, our big successes are a while ago. We have Rollins as a second rounder as our most recent clear H.S. success. We've spent a lot of first and second round draft picks on failed H.S. hitters. Especially bad and have been addicted to drafting H.S. OFs. This follows through in LA. When is the last time we developed a plus OF as either a H.S. draftee or LA signee? I may just be drawing a mental blank, but can't think of one. We've spent a lot of resources trying during the time span I'm trying to review in my mind. There were some, decades back who were injured soon after joining the MLB Phillies, or who had some success after we traded them. Even those were quite a few decades ago, as was George Bell whom we gambled and lost in the Rule 5.

What? Have the Mets now also backed away?
