Ross is good and should be starting all the time, but he's hurt for an unknown amount of time.
Piazza would be signed for 1 year, and it's basically just as insurance. He can still play.
Piazza allows us to get another catcher without giving up talent. That's the most important thing. Would you rather have Bako starting? Because that's what is going to happen.
I'm fine with Hannigan/Tatum. I'd rather have them than Bako, but Bako is Dusty's guy, and I don't see it happening. Hannigan is on the 40 also, so he really should be here instead of Bako.
