RENTON — Sunday marks the 41st renewal of the Seahawks’ oldest rivalry.
Oldest, anyway, in that the Seahawks played the Cardinals — then in St. Louis — in their first NFL regular season game on Sept. 12, 1976 at the Kingdome.
The two teams wouldn’t play again for seven more years and then intermittently until Seattle moved to the NFC West in 2002.
Of late, it has been maybe the oddest series of the Pete Carroll era. Set aside all the strange things that have happened in the games themselves and just consider this — the Seahawks are 6-2-1 against Arizona under Carroll in Glendale, but just 5-4 in Seattle.
