Holmgren shares ties to the Raiders' front office through Reggie McKenzie, the team's embattled general manager who rose up through the ranks under Holmgren in Green Bay.
NFL Media Insider Ian Rapoport noted on Sunday's NFL GameDay Morning that Oakland is on the hunt for a "rock star coach," confirming that the Raiders "will target" Jon Gruden, a longtime favorite of team owner Mark Davis.
Like Gruden, Holmgren also fits that so-called "superstar" model. On the heels of a disastrous but lucrative front-office run with the Browns, the 66-year-old Holmgren told The MMQB in July that he's "quote-unquote retired," before tweaking that to "semi-retired."
In other words? Stay tuned.
