Yes good points on the back up catcher.  But the fact that the Jays had a revolving door of back ups that ranged from  horrid to terrible to garbage shows they knew they had an issue which they failed to address.  They signed Salty, got rid of him, brought him back and then dumped him again.

On the injuries thing, this team got off to a garbage start with a full and healthy line up.  Once the injuries started, they had an excuse for the lousiness.  But the order of events is important.
