agree with trying to upgrade outfield. Caveat = I have not done H2H leagues, but I would also be concerned about Figgins pt when Kennedy returns. If he gets enough at his various positions, that might be okay, but it doesn't look like you have that covered in the event that he sits very much.
Also, suggest that you try to trade Kolb for an upgrade to SP. I think Kolb is out of a job by Father's Day because he's just not good, AND if Smoltz wears down, maybe they move him back to the pen. This presents all kinds of options for you to consider.
