This is a legitimate concern. The bench right now, assuming Espinal is starting at 2B, is two OF's who can't hit, a backup catcher who can't catch or hit, and then Biggio who is versatile but only really playable at 2B. Bench depth is fairly easy to get at the deadline, so I'm not really stressing that, but Charlie with Tapia, Collins, and Zimmer at his disposal is terrifying.
