Amid widespread speculation that the Raiders not only want Jon Gruden to be their next coach, but think they could make it happen, there would be complications.

ESPN, for which Gruden works as the analyst on its “Monday Night Football” broadcasts, reported Saturday that Raiders owner Mark Davis is prepared to make a lucrative offer to Gruden that potentially could include an ownership stake in the franchise. If ownership of the Raiders is involved in Gruden’s deal, the arrangement would have to be vetted and ratified by other NFL owners. It would require the approval of at least 24 of 32 owners league-wide.

Gruden, 54, coached the Raiders between 1998 and 2001 before being sent to the Tampa Bay Buccaneers in a rare trade of an NFL coach. That swap was orchestrated by late Raiders owner Al Davis, Mark Davis’s father. Gruden won a Super Bowl title in his first season with the Buccaneers, beating the Raiders, and lasted in Tampa through the 2008 season. He has not coached since, although there has been nearly annual speculation about his prospective return. He turns 55 in August.

The Raiders can offer not only an overwhelming financial deal and the chance for Gruden to return to the franchise, but also the opportunity for him to coach a contending team with a productive quarterback, Derek Carr, that is about to make a move to Las Vegas.

ESPN announced Monday that Gruden remains scheduled to be in its broadcast booth for its telecast of Saturday’s Titans-Chiefs AFC playoff game in Kansas City.

Gruden reportedly has begun lining up a prospective coaching staff. Some within the league believe it’s possible that his defensive coordinator will be Paul Guenther, the widely respected defensive coordinator of the Cincinnati Bengals. But Guenther also could be a head coaching candidate in Cincinnati if Marvin Lewis does not remain in the Bengals’ job.

Mark Davis and the Raiders will have to deal with the fact that Gruden has considered other jobs in previous years without actually taking one of them. He was linked in recent weeks to a possible return to Tampa. But the Buccaneers told their current coach, Dirk Koetter, that they will retain him, prompting speculation that Gruden chose the Raiders instead of Buccaneers.

Another complicating factor for the Raiders is the Rooney Rule, which requires each NFL team with a head coaching vacancy to interview at least one minority candidate. The Raiders must comply with the rule, even amid the widespread belief that they already have settled on Gruden as their coach, or face disciplinary measures by the league.

In 2003, former NFL commissioner Paul Tagliabue fined Matt Millen, then the president of the Detroit Lions, $200,000 for failing to interview a minority candidate before hiring Steve Mariucci as the team’s coach. Tagliabue told NFL owners during a meeting that year that any future violation of the rule could result in a fine of $500,000 or more for conduct detrimental to the league.
