I have a Yahoo league that has worked well and is semi high scoring. We use QB, WR, WR, WR, RB, RB, TE, W/T, K, DEF, BN, BN, BN, BN, BN, BN. The advantage is that you have a lot of flexibility in the passing game and it can add strategy in picking good depth at WR and having solid TEs. We actually discussed dropping one of the RB positions as there are so little good players or teams that rely on one primary running back anymore, but decided that keeping 2 adds to the strategy and makes bye weeks more interesting. Staying at 10 teams, t here seems to be enough players out there to have a pretty solid team if you draft good and are following trends and injuries constantly.
