After a quick recovery from major knee surgery, Peterson's game and fantasy numbers have strengthened throughout the NFL regular season. Peterson is averaging about 164 total yards and a touchdown in his last four games.
The Vikings are coming off of a bye week, so Peterson should be rested and ready to go at Soldier Field. Peterson has actually struggled against the Bears over the past two seasons, only playing in one game each year due to injuries. Last season, AP scored a touchdown but only rushed for 39 yards in Chicago.
Peterson appears to be a different player this season, evoking memories of 2009 and 2008 when he was among the elite fantasy players in the NFL and gained over 100 total yards twice per year against the Bears.
The Vikings will need Peterson to have a big day with Percy Harvin out for the game with an ankle injury. The loss of the dynamic Harvin should help the Bears defense load up on Peterson and force Minnesota quarterback Christian Ponder beat them.
Even with the full attention of the Chicago defense, Peterson's play of late makes him a valuable fantasy play this week.
