Here is my way of looking at it.
While Many QBs may end up at the top of the overall points list at the end of the season, that does not make they a good value in the first round.
RBs are huge in round one mainly because the difference between the top teir and the mid tier is greater. Every team has a full time QB. Not many teams these days have a Full time RB. Many have gone committee. If you can get a full time every down RB, that is huge.
A Top QB might average 22-25 point a week in your league, but that does not make him more valuable than the top tier RB who averages 18-20 points a week. That is because in the mid rounds, you can get a QB that averages 17-19 points a week, but the RBs at that level might only average 8-12 points a week.
WRs are a plenty. I personally wont draft a QB till round 7-8 at the earliest, as I dont see the value at the position. I think a 7th round QB will average maybe 3-5 points less per week than the first round QB. I would take the first 5 rounds and just pick best available at either WR/RB.
