If Pablo and Castillo were starting and were playing like All Stars, we still only have Young, Holt, Shaw, and Hanigan on the bench. Regardless of the contracts of Pablo and Castillo, there is only room for one middle infielder on the bench. So once again, no clog.
And the fact that Pablo and Castillo still have multiple years left on their contracts is exactly why they needed to be given a chance to prove themselves in real games. None of you, including Farrell, Dombrowski, and Henry, are considering long term ramifications.
Panic, panic, panic.
