Vance Joseph served as HC for the Broncos previously. He was fired not long into his tenure and was replaced by Vic Fangio (Joseph is a rah-rah motivational players coach, when that didn't work they went to the other extreme with the HC as old school Woody Hayes style dictator leadership style with Fangio, that didn't work either and ofcourse Hackett was an embarrassment when they swung back in the other direction). Joseph then returned to Denver as DC under Sean Payton and he is doing well in that role for us. It has turned out not to be awkward as people thought bringing back the former HC of the club to serve as DC for the team under a later HC. He has done well as DC.
He's a good DC that really didn't do well at all as HC. I dont know if its a Peter Principle issue or he just wasn't ready.
If you guys hire him, it's basically to be Caleb Williams buddy. He's a players coach. Sometimes that works, Pete Carroll is a players coach too but Carroll is an effective HC and is a good CEO. I dont think VJ is but who knows.
