How they proceed with hiring a DC will be very telling of BK's job security beyond this season. If they pursue and hire big name DC, then it stands to reason that BK likely gets another year to get the program on track.
If they keep Hudson in the interim role through the season, it seems likely that BK will be gone.
I would think that it would be tough to lure a big name DC without promise that BK's job (and thus the DC job) is secure. Nobody is going to want to hitch their wagon to a dead man walking.
