Whither Zaun?

The Yanks are apparently in the running to get Greg Zaun as a back-up catcher. This would actually be a back-up to get excited about. He would not create a hole in our line-up when Po sits. There's apparently competition for his services, but hopefully, Cashmoney Green can get something done here. I hope this wouldn't derail any attempt to land Nick Johnson, as the deal I heard would include taking back Brian Schneider to back-up Po. The more important piece would be getting OBP Jesus back. So, if Zaun would screw that up, pass.
