Klint Kubiak has a second interview with Seahawks on Jan. 17th [Kubiak is in the driver seat for Seahawks OC job per Mike Garafolo]

Cleveland has no concerns over anyone

Seattle has a very young coach.

I am not saying KK is bad by any means, he would not be considered a top coordinator in the league either by any means.

I am sure there were a lot of variables that led to him being so bad in the 2H of games.
Also, his connections (and last name) virtually guarantee he will always get a job.
