I think closers are your weak spot, not starters. Lackey and Zambrano is a nice top, and Buehrle won't blow anyone away w/strikeouts, but should have a solid ERA below 3.50, as well as a good many wins on that team.
Gagne's velocity and health is always a concern, so Baez should be on the back of your mind if he's still on the WW. Are there any closers on your WW? Rodney and Burgos are 2 guys worth a pick-up in your case I think, or maybe even a Miceli or Bowyer.
Here's my team. Help me out:
