What I would have done if I'd realized their worth, is wait until the first one went off the board and then make my next pick or two SP,RP players. As it stands, I think most of them went in free-agency, which means that either no one realized their value until after the draft (highly unlikely) or the the person or persons who appreciated their worth knew that most of the rest of the league did not.
This won't be an issue for anyone next season because the scoring will probably be different, and more people will be aware of it if it's not before hand.
