I'm not too concerned about the hitting at the moment. There are always a few guys that unexpectedly have good seasons or are called up from the minors. Last year, I had a lot of guys like Adam Jones who struggled at the start of the season and I probably kept them on my roster too long. I'll probably burn through more hitters this year.
The key for fantasy baseball is just staying on top of your roster for the whole year. I get most of my talent infusion through FA's rather than trades.
