Boldin and Davis weren't tabbed by the Draft Dominator as fantasy stars???
That pretty much sums up the value of VBD. It is only as good as your projections, which are little more than guesses. VBD wasn't going to help you get Boldin or Davis, and it likely stuck you with chumps like Burress, K Rob, Driver, Price and Moulds as 'top WR's'.
For people new to fantasy it might be a help, but anyone who has played any length of time knows when to take a top RB, a top WR, a TE, your starting QB and back-ups, etc.
Another tool to use with some discretion, but it isn't a magic program to win your league with.
