They have to interview several coaches whether they already know who they are going to hire.
It may be that they have to interview a black coach too, or it looks good, then they hire who they already knew they would.
A lot of coaches get interviews even though they never get hired.
I think it is funny because if one is a good DC or OC it doesnt mean they would be a good HC or leader.
Yet owners keep hiring them, and they keep failing .
Just look at linehan and marinelli, both are decent coordinators, and with the right talent they look real good,
but as HC's they were horrible.
