Jared Cook or Logan Thomas? PPFD league

Jared Cook or Logan Thomas??? It is a points-per-first-down league, most similar to a half-point PPR.

Starting WR are Allen Robinson & McLaurin, RBs are Elliot & Jacobs, and (2) flex spots are filled with Kareem Hunt and Nelson Agholor. I am projected 26 points lower (143 to 166), so probably need upside to overtake. Thoughts?
