Not ancient history but different president, different GM, different development staff. And honestly I wouldn't read that much into it, the kid was only ever in the GCL.
But sure, at the same time, if the Phillies still have a mentality that overlooks an obscure Australian signing compared to a prize LA signing or a high draft pick instead of looking at the player that's in front of them that's not good (and they did it with Vierling too). They are hardly the only team with that problem, but the Rays, of course, are a team without it. Whether they had a better evalation or Mead or just saw him as clay when they needed to clear a 40-man spot, they're better at handling the clay.
We just don't know how many people still are in this organization over the course of four development directors in 11 years, and almost as many Presidents, GMs and scouting directors! We don't even know how much has changed just in the last 18 months. Hopefully more than not, but until proven otherwise, it's the same franchise (and the same owner for almost 30 years with no real sign that he has a different vision, just a checkbook).
