Gibson isn't a kid in baseball terms. He's 27. As far as Santana goes, many felt last year was way over his head with his BABIP over .400. Now it's .286, so yeah, he's dropped. On top of that, he's wasn't a top prospect nor was Arcia. I don't think either was ever rated top 100 by any major prospect listings. Some people are screaming for the top prospects to come up.
