I absolutely hate picking in the middle. I play in a league of 8 and this year i received the fourth pick. This sucks because I don't know if I'm gong to get a great QB or RB. I really really really want Jamaal Charles and it sounds unlikely that he might slip to me but I play in a very unpredictable league where last year QB's went first. Im hoping for the same this year especially with the success of peyton manning. However I am debating with picking a WR first, something I have never done. If The first 3 picks go Charles, McCoy, and Peterson, i could get either any QB of choice but there are plenty of good ones later on so I probably won't do that, or I could get Calvin Johnson or Demarlyus Thomas. Just kinda looking for advice on choosing a WR first and what it means i do in the next rounds.
