So, here's a twist plot. McDaniel steals BOB as OC.
It's not like BOB is struggling to find open spots in NFL.
I think BOB's interview with Jags didnt' go well because of the common issue: Trent Baalke. He is very disliked in NFL circle. Nobody wants to work with him period. I suspect BOB didn't want the job because of GM.
I think BOB is being selective but at same time keeping open mind. He's looking at who's the GM, the culture and etc. I wouldn't be shocked if he get New Orlean Saint interview, Raider interview as OC, and Patriot as OC. If options aren't good, he can come back and there will be a better options next year.
