The elephant in the room with the Jim Knowles hire is that someone on the current staff needs to be let go. Who's it going to be?

Common sense would dictate that since Knowles is also a linebackers coach (and due to the incredible underperformance of the LB room) that Washington is out. That said, the lack of any comments have made me wonder if there's another coach on our staff that is being vetted for another position elsewhere? Thoughts?
