In redraft leagues the RB, RB theory of drafting is dead. Been dieing for awhile, I think it is dead now.
My Jammal Charles/ Matt Forte RB/RB selections last year seem to indicate that RB/RB is not as dead as you think.
I personally think that the lesson people need to learn is that nobody should follow a "theory" and should be flexible to take advantage of what the draft is giving you. I like to tier each position based on ADP so that I know what to expect in each round and at what positions. I star players that I really like and would take earlier than their DP sugest.I never marry myself to certain positions at certain points, but I do like to make several senario's of what my team could possibly look like. I will take a value player, but only if I truly like the player. I won't take a player I don't believe in. In the mid to late rounds I begin taking guys with major upside (Josh Gordon). Hit on just 1 or 2 of them and it will take your team from solid to elite. The ones that do not work out are tossed back and you make agressive wavier wire moves.
Last year for my team it was a perfect storm....both Charles and Forte fell in my lap, and I was trageting both knowing that each would see a major bump in receptions. I took a chance on Josh Gordon that paid of huge....and when I had a pick that didn't work (RG3), I made a wavier move for Nick Foles that paid off.
