It’s been two autumns now since Russell last played a down of organized football. This fall, when capable quarterbacks have been in high demand and short supply, he’s gotten no calls. The Raiders lost his successor, Jason Campbell, to a broken collarbone on Oct. 16, and last week they acquired 31-year-old Carson Palmer, who had chosen to retire rather than play for the Bengals. Oakland sent Cincinnati a first-round pick in 2012 and a conditional second-rounder in ‘13, and will pay him a guaranteed $7.5 million over the next two years. Yet Russell still counts himself among Mobile’s legion of unemployed.
