Fantasy Football Questions?

with ben roethlisberger now having one good performance, one mediocre performance, and one bad performance, is it time I give the start to J.T. O'Sullivan. I am currently 1-2 after a horrible week, and need a spark. Ben is playing against the Ravens at home, but i think there is much more upside in starting JT, because he wont just manage the game. Also i have 3 must-start backs heading into week 4, Larry Johnson, Mike Turner, and Willie Parker, and a pretty good Chris Perry. Im starting Turner no matter what, now KC plays denver, and CIN plays Cle. who would u start. I know its early but some help would be nice, thank you
