Right. Why can't they add players (who make sense, not just anyone) to the MLB roster, and if they and your incoming prospects play well, you have a pleasant predicament of multiple good players for a few positions. Trade them for pitching. Be creative in some way, shape, or form. Some people are convinced that the team has to be terrible and cheap until the prospects are ready.
And another thing - we are people who like baseball. This does not have to be some soulless, objective exercise. My summers are more enjoyable when I am watching a winning MLB team. That simple.
