Due to a series of trades, I wound up with the overall number 1, 7, and 18 picks and lost my third round pick in a 12 man PPR league. I hope to walk away from those picks with 1 top RB, and 2 top WR's. This is my first time in a PPR league, so I'm not sure how to value each position. Anyways, when should I pull the trigger on a RB? I can either draft my choice of RB at 1, then whatever receivers are available, or draft Brown at 1, then whichever of the top RB's fall to 7; or take the top WR's at 1 and 7, then hope that a good RB falls to 18. What are everyone's thoughts to ensure that I get the best value for each pick?
