To each their own. If we draft 1-6 we'll probably take a RB first. Otherwise, probably stick with wr/wr. I guess we all have our own idea of what a "serviceable RB is". If we wait til rd4 to draft RBs then our definition will be different than someone who is taking RB in rds 1 & 2 just due to we will likely be stronger at wr.
Good luck to all varying strategies. Interesting how this actually pans out when you get in drafts. See? We're not as inflexible as we may seem. Though we may set out w/ a particular strategy, we do indeed adapt to each draft as it unfolds. Now let's just hope none of our early-round RBs hit land mines.
We've done a few DCs so far and here's how we fared in the early rounds (don't recall exact rounds selected, but roughly in draft order):
Slow Draft 1-14th (according to plan, WR/WR/QB/RB): Calvin, Marshall, Romo, Jacobs, Housh, Winslow, Bradshaw, LT.
GAMERS 1-13th (couldn't let Turner go by): Turner, Marshall, Boldin, Cutler, Moreno, Jacobs, Evans, Bradshaw, Holmes
GAMERS 2-10th (we didn't think a top-7 QB would fall to us in rd3 so we took one in rd2): Fitz, Manning, DWilliams, Celek, Ward, McFadden, Housh, Slaton
Still highly unlikely that we'll take TWO RBs early in any drafts. Too much risk on too volatile a position, IMO.

I like our Jacobs/Bradshaw combo in two leagues - regardless of which one ends up starting or which one we drafted first. 
) probably makes this league the riskiest for us. But if Cutler plays well most weeks, I like this team. 
Check back w/ me in 3 weeks and we'll know better.
