One minor storyline from the Arizona Cardinals upset of the Pittsburgh Steelers that got some national attention was the Patrick Peterson “revenge game” angle. Peterson, a once-beloved Cardinal, is now almost universally disliked, if not hated, among Cardinals fans.
But is he the most-disliked former Cardinal? There are certainly several other contenders—although I will say that given how hapless this franchise has been for much of its tenure in the desert, a lot of ill will toward former Cardinals more takes the form of sadness than outright derision.
Still, there are definitely several former Cardinals who remain the targets of fans’ ire, from draft busts to malcontents to actual criminals.
