Palmer missed the Arizona Cardinals' two losses to the Seattle Seahawks in 2014. The quarterback returned from a torn ACL and is playing at an All-Pro level. Seahawks coach Pete Carroll said he's never seen Palmer play better than the quarterback has in 2015 -- remember Carroll coached Palmer when the QB lit up the college ranks. Palmer has utilized Bruce Arians' stretch-passing offense with aplomb, taking advantage of mismatches with Larry Fitzgerald and John Brown. The Legion of Boom hasn't been as thunderous this season, but still own the NFL's No. 2 rated pass defense. Richard Sherman shadowing opposing top receivers is an intriguing twist. It will be interesting to see if Sherm trails Fitzy at all Sunday. If the LOB forces Palmer into turnovers Sunday night at CenturyLink Field, the Cards' lead in the NFC West will feel awful small come Monday.
