I can't speak for what the local newspapers were saying, but nationally there simply was not that much hype around Campos. In no way was he ever really considered some elite prospect or ever looked at as a future franchise cornerstone.
And it's really weird to frame it as some huge mystery how he slipped into the US. He defected from Cuba years before he signed with the Tigers. He defected, like every single other Cuban player, when he had the opportunity to do so. We don't need to know the exact details of how it all went down.
