As special of a player as Marsh might/could be, the same is true/could be said about O'Hoppe. Which, makes the trade a wash in that respect. But then when you add in the difficulty (as other posters stated above) of finding/developing a catching propsect with the offensive potential like O'Hoppe, makes it even more favorable for the Angels. Then considering the acquisition of a gritty/intense/Erstad-like prospect in Moniak & a raw/potential upside prospect like Sanchez...I think makes it an overall win for the Angels.
