  File- This Sept. 9, 2012 file photo shows Seattle Seahawks quarterback Russell Wilson (3) trying to escape the reach of Arizona Cardinals defensive end Calais Campbell during the second half of an NFL football game in Glendale, Ariz. The Cardinals are leaning on their defense, even if the players won't say so. Arizona is the only team in the NFL not to allow more than 21 points in any game. (AP Photo/Paul Connors, File)
