I’m not sure I’ve ever seen anything like this. Where while the previous head coach still held the job and before the next coach is even allowed to accept an offer from a team, there are already reports and rumors everywhere as to whom he is looking to have join his staff.
That’s the situation we’re in right now with the Raiders’ coaching situation. It can be tough to follow every report and rumor that comes out, here is the currently reported/rumored staff

Rich Gannon turned down the Raiders QB coach position to stay at CBS.
Tight ends coach Bobby Johnson and Safeties coach Brent Vieselmeyer were originally expected to stay on staff (report), but recent reports say they are now expected to leave.
Former Lions DC Teryl Austin had reported interest from the Raiders, but is hired by the Bengals.
OL coach Jeremiah Washburn (was rumored but he has been hired by the Dolphins)
There was a report the Raiders were interested in Jets OC John Morton but that never materialized.

Bisaccia was his Special Teams Coordinator for Gruden’s entire head coaching tenure in Tampa. Olson returns to the Raiders as OC. He was a QB coach under Gruden in Tampa in 2008. Brian Callahan is the son of Gruden’s former OC Bill Callahan. So, Gruden is clearly looking at bringing in some trusted names with whom he’s familiar.
The former staff was kept on staff initially and allowed to seek employment elsewhere. Some of the above names are coaches who decided to stay and Gruden decided to keep them on staff.
