My 10-years and running keeper league went to 1 RB, 2 WRs and a FLEX this year, because of this fact. My 12 team league actually starts 3 RBs and 4 WRs and I don't mind it too much. It's very rare for any team to have 3 quality RBs starting (obviously) so it kind of evens out, but if you do have 3 quality RBs you have a major competitive edge. Right now I'm starting Foster, Branden Oliver and McFadden and its been working out ok. The worst thing about my league is we also start 2 QBs. Do the math...12 teams, 2 starters, 1 bench guy for injuries/bye weeks thats 36 QBs. Obviously only 32 start in the NFL so there are always teams in my league that literally are forced to start a backup hoping that the starter gets injured or replaced during the game or starting someone like Michael Vick and hoping they bring him in to run the wildcat or something. When your opponent has 2 QBs each putting up 20+ points and you start a guy who doesn't play, its almost always a guaranteed loss. League sounds like a mess. In a 2-QB league, I'd draft a QB first round every time, especially top 5-6. You have to have at least 1 elite QB in order to win. And if you get a Rodgers, Manning, Brees, Luck, you can wait a little longer for your 2nd QB and make up your potential disadvantage at RB while everyone is scrambling for the last QBs.
