Is francisco rodriguez for ZImmerman a good trade?

I think whoever is getting Zimmerman in this deal, will be getting the better end of things. That said if the person giving up Ryan had another good 3B and really needs a RP then this trade would be good for him also. Both players are playing great baseball and are both ranked near eachother on the Y! ranks list. So as you can see there are more things to take into consideration, other then what info you have provided me with. But the trade seems to be fair. GL
