I don't think the trade is as bad as some of you are making it to be.
While Schneider is close to an automatic out, he has been one of the best catcher in the NL fielding wise.
Ryan Church has an underrated bat (pretty amazing road splits) and provides very good defense for a corner OF.
I still wouldn't have done the deal because one shouldn't be trading away a young 5-tool player for fill-in players, but this certainly improves the Mets O and D for next season.
