GM's on other teams aren't stupid. They see another team for a big need at a certain position, see that their Minor Leaguers are a couple of years away, they will ask for a lot.....at this moment. Longer you wait you could get someone decent, for a salary dump, or FA's to be, or teams that feel they might want to bring their kids up at July 31, might not cost you so much.
Patience, at this point, I know it stinks, but with all the injuries on this team this year, were in 1st, I'm really shocked. Doing OK.
