Understood. I don't want Kingsbury either. I don't agree that he was wrongly fired in Arizona. He was a rush hire and the results showed it. He's at best a coordinator and at worst a QB coach. He's no HC.
He seemed to be making that terrible Arizona team better every year and even got them to the playoffs in his third year. The year he got fired was the year he lost Murray for almost the entire year.
I'm not saying he's near the top of my list, but he's an interesting option. But I don't know if he has the personality to be a head coach.
