A dark cloud is hanging over New York today, so let's lighten things up with a boatload of rankings, previews, and tiers.

NBC has rolled out our Fantasy Fix position previews and my running back tiers are live on the main site. Below, Tiffany and I talk receivers. Check out the fancy intro! In a PPR league last night, I went WR-WR-WR in the first three rounds as an experiment. I still like my running backs, so we'll see how it works.. (I had the last pick in the first round.) I may post more of the videos on the blog, but all the positions are ready if you open the video player.

Which Defense will bounce back huge in 2008?
