It's less about that and more about how Adell is a very risky prospect in an org that sucks at everything. Also, yes, I'll learn my lesson. Anyone over 30 is basically Miguel Cabrera and every single one will just fall off a cliff for one reason or another. David Ortiz has never played baseball, no idea who that guy is.
We should call it the Miguel Cabrera rule where you need to trade any star the moment he hits the age of 30 for any prospect that comes your way, immediately. No shopping around allowed.
