Nick Foles' epic performance saw him shoot up our QB power rankings this week.
Elsewhere, Alex Smith and Terrelle Pryor took tumbles.
Our rating is a composite of three advanced stats: defense-adjusted yards (DYAR), total QB rating (QBR), and win probability added (WPA). Each stat accounts for one-third of the rating.
UNRANKED: Seneca Wallace, Green Bay Packers*

Team record: 5-3
Thing to know: He averaged just 6.0 yards per attempt in back-up duty last week.
*Not enough data to create a ranking.
UNRANKED: Case Keenum, Houston Texans*

Team record: 2-6
Thing to know: These last eight games are Keenum's audition for the starting job next year.
*Not enough data to create a ranking.
30. Carson Palmer, Arizona Cardinals (previously 27th)

Team record: 4-4
DYAR: 34th
QBR: 32nd
WPA: 42nd
Thing to know: He has a winnable game to put the Cardinals in the playoff race against Houston this week.
