I will have links here for your Week 17 games and also for Playoff Challenges.
The first article I would recommend you read is an article about the Playoff Challenges coming up next week. Fantasy Knuckleheads has a solid read: http://fantasyknuckleheads.
Junkyard Jake's match-up article is always a great place to go for your Week 17 line-ups. I really like how RC uses stars to rank the players. http://www.junkyardjake.com/Matchup/
Chet's thefakefootball.com has a really nice article on defenses to exploit and some player recommendations: http://thefakefootball.com/2011/12/27/defenses-against-running-backs-week-17/
Ryan at lesterslegends.com has some solid rankings. Let's start with his WR rankings: http://lesterslegends.com/2011-fantasy-football-wr-rankings-week-17/ but you can find more rankings on his site.
You also need to go and join a Playoff Challenge league. I have a free one going on and the winner gets a draft guide for next year: http://www.hattywaiverwireguru.com/2011/12/hatty-waiver-wire-guru-nfl-playoff.html
Good luck! I will have Playoff weekly rankings for you.
