Week 6 DL pick em?

My DL choice for this week is Tuitt or Fletcher Cox. They both have poor matchups I believe. Tuitt seems more steady but Cox has a bigger 'playmaking' upside. I know you have Cox ranked higher this week ...but any thing else I'm missing?? Thks..

1 pt solo, 3pts sack, 1 pt TFL, 1 pt Pass defend/deflect, 3 pts for FF, Fum Rec, and intercept

Tuitt ... solid tackle guy, I generally take tackles guys and there is solid chance of a blow out... aka AZ will run in the 2nd half.

AZ isn't giving up sacks, so youd be banking Cox gets a sack in slightly better match up
