And although the 2018 version of the Raiders would be far more talented than the two-win team that Shell was the steward of, Gruden's high-percentage dink-and-dunk scheme would be hard-pressed to take hold one season after current offensive coordinator Todd Downing has failed so miserably with the same approach.
According to a report from ESPN's Adam Schefter and Chris Mortensen, the Raiders are preparing to make Gruden a massive offer that could include an ownership stake in the franchise. Following the Super Bowl run of his first season in charge, the Bucs never won another playoff game under Gruden.
Former head coach of the Raiders and now football analyst Jon Gruden shown at a game between the Saints and Raiders November, 2012 in Oakland.
"I don't want to sit here and speculate", Gruden told the network. "I can't say I haven't taken any phone calls".
An ownership source said owners might not be so quick to approve the deal, because they wouldn't want to establish a precedent. "Im here to help people".
The year prior, the Raiders also gave general manager Reggie McKenzie an extension, and it's not known how Gruden's hiring would affect the general manager in terms of the draft and free agency. The Raiders were a popular preseason pick to be a contender in the AFC, but have fallen to 6-9. Rapoport would add that Davis and the Raiders have tried to bring Gruden back before, albeit unsuccessfully.
The elephant in the room is that the Raiders now have a head coach in Jack Del Rio.
Sources have said Gruden has made calls to coaches around the National Football League in an attempt to put together his staff, although he has done the same in prior years but never followed through with an of the different opportunities that were presented to him. After ranking top 10 offensively in points and yards last season, they are 23rd and 19th, respectively, this year.
So, it's natural to remain skeptical about Gruden leaving ESPN, but this Raiders rumor is certainly an interesting one. But again, Gruden has not coached since 2008.
The reasons for the Buccaneers deciding to keep coach Dirk Koetter possibly are becoming clearer.
