re: No more K & DEF, should I replace them with another position?

If some prefer to not use kickers, that's fine... to each their own. But I wouldn't use randomness and single out kickers as a reason to omit it. The randomness applies to each and every position. Why not limit randomness by eliminating running backs as well? You get my point.

Randomness makes fantasy football... fantasy football. That's why it appeals to the masses. Everyone, regardless of experience, has a chance to win. You take that away, you lose some of that appeal.
