Should I make this fantasy baseball trade?

id give up milton bradley and mike Gonzalez from the braves, and get andy pettite, brian fuentes, and sean marshell... the last of whom i might just drop anyway. Is bradley worth the risk? its a head to head league and my starting pitching is lacking a bit and if i got petitte he would probably become my ace. Its a sixteen team league so talent is stretched pretty thin. My other outfielders are Jason Bay and Coco Crisp
