#4 is my preferred draft spot this year. AD, MJD, Forte, and Turner are pretty clearly the top 4 draft picks this year. In the first round, you'll get whoever falls to you from that group. Then in the second round you'll have a good shot at someone like Portis, Barber, or Westbrook. And ideally in the third round you'd be able to grab a top WR like Jennings, Steve Smith, Wayne, Roddy White, etc.
In a 12 team league, I'd take a core like that any day.
