I went RB/QB/RB/RB/TE in my 12 teamer (had 1.01 and 3RR), my WRs are rough!!!
Honestly wouldn't recommend it
Who are your WRs and are you in a 2RB/2WR/Flex league or just two RB. Makes a big difference.
FWIW, I ended up, shockingly (to myself at least) going RB, RB, RB, QB, TE, RB. I expected to wait on QB, though as the run happened right after, this ended being a decent move. TE was Gronk, who I never thought would drop to the fifth, but he did and I'll take the chance on proven upside. Decent chance he will be at at least a FF WR#2 level, if not better, by week 4-5, if I can sustain the early games.
My WRs - I'll start two of the three
A Boldin, SF - Hardly spectacular, but he has a history of producing when needed, and he's needed. If Caep's so good, even with V Davis, the #1WR should get enough looks and enough redzone looks to be workable.
James Jones, GB - Big upside, has shown he can get to the endzone and there are a lot of yards AND TDs in that offense. Obviously concerned re: consistency, but these are rounds 7, 8 and 9.
C. Givens STL - Could be the traditional #1 on an offense that many think might take a step forward, and again, showed last year he can do it in game. But hardly "proven"
Now, hardly D Thomas and Wayne or Garcon, and it's not for everyone - but with the players presented to me when they were, I think those three WRs as my "worst" two starters overall will make my going all in on RB (also got Lacy) worthwhile. And certainly some trade opportunity.
