Matt has been busy:
Question for Matt - there are definitely lots of arms that are rule 5 eligible next winter. But even in the better group of Cabrera, Aldegheri, Castellanos, and McGowan are we really sure that they need to be protected? They are good but not great arms for the most part and also none of them are really ready for a major league role yet. I just don't think teams stash pitchers any more because they need them. Could Cabrera and Aldegheri survive as the long man in the bullpen? Sure, but that would not be ideal even for a rebuilding team.
It does make sense to trade some of the rule 5 eligible. It just may not be quite as high a priority since not protecting them to get another year of control has been the Phillies rule 5 strategy in recent years.
