"And in any case, Falvey wasn't really hired to sign pitchers. He was hired to develop them."
I don't agree. This is semantics. They go hand in hand. If you trade for prospect pitching, that has been partially developed in other orgs, you can't really take complete credit for developing them. That is just about all the pitching in the pipeline. Traded for prospect pitching. Every FO is hired to sign pitchers. Prospects and free agents. These guys were not only about developing, but identifying! It seems, with the success of those they let go or traded away for virtually nothing, and the failures of those they have chosen to fill immediate needs, they could get better at identifying. A lot better.
