Should this baseball trade be vetoed?

I was recently offered Granderson for my R Martin. Now I obviously excepted immediately believing i win hands down, but the other guy has no catcher and a log jam at OF. I repeat this was offered to me, is it really that bad?? Should I sucb to a couple whining managers on this case. The only protest is coming from the guy I'm trying to catch in 1st, I'm sitting at 2nd. Thanks for thoughts
