It's good to see that you took Davis as a handcuff to Lewis - I think he becomes the feature back very soon. In a 14 team PPR it looks like you did OK - not crazy about Lewis or Benson, but Benson may prove me wrong this year. I'd say you're starting QB and Receivers are above average, and should net you solid points in a PPR league - especially with passing TDs worth 6..
1pt - 20 yd pass + 3 pt bonus at 280 yd pass
1pt - 10 yd rush + 3 bonus at 100 yd rushing
1pt - 10 yd rec + 3 bonus at 100 yds receiving
6pt for rush/rec TD
4pts for pass TD
1-4 RB, 1-4 WR, and 0-4 TE - so it's like 1 RB, 1 WR, and 3 Flex spots
