For sure it's harder, but that's because of the wider range of outcomes, but that's where the gpp leverage comes from.
Maybe I am off base, and others can chime in too.
FD is more heavy towards TDs, so IMO the best place to start is with teams with high totals and look for low % ownership guys there. Sure any given Sunday, but the odds of Trubisky outscoring Russ or Dak next week is a lot smaller than say A.Rob outscoring a higher owned Wr in the Dallas/Seat game. Floor for wrs and tes is 0-6 points.
