Anyone doing this this year, or done this in the past?

I'm a bit clueless when it comes to NFL (doing a fantasy team is an attempt to fix that), so did a bit of reading up on decent rookies and tried to pick an "under the radar" team. Sadly, I've ended up being shafted by the draft and so I'm frantically bargaining and trying to sneak some free agents.

Any recommendations? (I'm not counting "try a real sport" as a recommendation)
