I've been playing fantasy since the 90's but have never done a keeper league so I'll just comment on your half ppr league.
QB - A (great one two punch)
RB - B (Love Robinson and Etienne. Not sure what to think of Z. White but an okay pick. Don't love Benson behind a running QB and an established RB in Connor. Also, no RB coming off a torn Achilles has ever been fantasy relevant the following season so the Dobbins pick was a wasted opportunity.
WR - C+ (I like the stacking with Stroud but taking two Texans limits both in terms of total weekly team points. Pickens is a great pick. I'm not crazy about Green Bay or Chargers WR's this year.
TE- B (It would be an A if they didn't draft Meyer in the top of the 2nd last year and Bowers had a better QB).
D/K - IDGAF
