Who should i drop: kazmir or lirano?

You might want to drop both. Liriano has been awful and Kazmir has been pretty bad as well. They may have a comeback, but later on in the year. I like Jair Jurrjens a lot. He has become the unofficial ace of the Braves' staff. You should sign him and get rid of Liriano. Then, sign John Danks and get rid of Kazmir.
