2012 Grid Challenge: Fitz, 49ers' defense

San Francisco 49ers fans seeking reassurance following a rough Week 4 will find it in Tom Carpenter's latest column for Gridiron Challenge players.

"The 49ers should be the best fantasy defense play this week in just about any format, and they come at a reasonable price in the GC," Carpenter writes for ESPN.com.

This would be a good time for those playing in our NFC West group to update lineups. My team has Aaron Rodgers, Peyton Manning, Arian Foster, Marshawn Lynch, Brandon Lloyd, Julio Jones, Vernon Davis, David Akers and the Green Bay defense going this week.

Another NFC West-related note from Carpenter, this one regarding Arizona Cardinals receiver Larry Fitzgerald: "Now he gets the Miami Dolphins, who have allowed more than 300 passing yards per game. Wind him up and let him go!"

The chart, from ESPN Stats & Information, shows leading wide receivers against Miami through three games this season.
