QB Scrap Heap

After losing W2 & W3 by slim margins, I can't afford to start Richardson W4. I just need 15 points from my QB to win these matchups, but IMO the best options available are D. Jones (Dal), Fields (Ind), and Darnold (GB). Other QBs remaining are Smith, Herbert, Dalton, Watson, and Cousins. From this lackluster group, who offers the steadiest chance of getting 15ish points?
