What I meant by my sarcastic remark is that picking the right players matters 100x more than the position.
That's not to say the position doesn't matter - picking a RB in round 1 when you already have a strong starting RB is, IMO, silly (I'm looking at you Donahoe). So is picking a kicker, punter, or special teams gunner in the first round.
Outside of that, though, it doesn't bother me what a team chooses to build through FA versus through the draft, as long as they have well-rounded drafts.
