For all we know, they are leaning toward hiring a particular individual but they feel they owe Campanile an interview based on his time with the Dolphins.
Also Fangio might have told them he wants to wait until he sees what happens with the Eagles before making a decision.
I assume if they really wanted one of the coaches they have already interviewed and that coach was ready to sign to be the next DC, it would have already happened.
I’m not worried about them missing out on signing a DC who will be an upgrade over Boyer. It will happen when it happens and until then, I ‘m not going to stress about it.
