I think it really comes down to the following draft theory:You get ahold of your projections. Either FBG, do your own, use another site you're comfortable with. Whatever.Then you begin doing ADP study. Do a ton of mocks for the league you're drafting. (I did 700 mocks for my main league this year.)How well do you know your league? If you have a good handle on how they draft, then you're ahead of the game. But you have to know what players are going where.Now the interesting part. You figure Rodgers is almost certainly going in the first round. According to the current years ADP, where are Brees/Brady and probably Cam Newton going?For arguments sake, lets say late 3rd early 4thIn general you will get RB3 or RB4 at 01.04. You can also get QB1. You can also get WR1.Assign the RBs and WRs to tiers. Tier 1 RBs and WRs go in round 1 and 2. Generally, in past years, the top 7 QBs are gone by the beginning of the 5th.Your projections have to be solid here. Because this is what you can't screw up.Say Aaron Rodgers vs Brees/Brady/Newton PPG difference is less than 1ppg according to your projections.Say, according to you projections, that the difference between WR1 (Calvin or Andre)/ RB4 (Rice/McCoy/Forte) compared to the tier going around where Brees/Brady/Newton is going is more than 1.5 ppg.So Calvin at 1.04 is a 1.6 ppg advantage over say Stevie Johnson at 3.08.But Rodgers at 1.04 is a .9ppg advantage over Brees at 3.08.Logically it makes sense to go with a RB/WR in the first round, and select a QB later on.If you can successfully spot excellent late round value (which isn't hard given the resources you have available on this site), then waiting until round 8 to grab Stafford/Roethlisberger at a mere 1.3 ppg disadvantage to Rodgers in the first, then you pack your roster full of RBs and WRs that consistently perform at an advantage vs your opponents.So if you have 6 roster starting roster spots for RBs/WRs (2RB, 3WRs, 1 flex) operating at a .3-.5 ppg advantage, you have a 1.8-3ppg advantage over your opponent. Subtract their QB advantage (1-1.5 points) then you nearly always have a slight advantage against your opponent. Bear in mind, Rodgers getting 6pts per passing TD is a scary proposition. But Stafford gets the same 6pts per passing TD. It also mitigates Rodgers rushing TD advantage. They're not worth 6 vs 4(passing). A rising tide lifts all boats, in this respect.So I take the BPA at 1.04. It's probably McCoy/Rice/Calvin Johnson. Statistically it's just a bit sounder to pack high end RBs/WRs on your roster and take a marginal disadvantage at QB.disclaimer: these numbers are theoretical and for the sake of the argument i'm making.
