I will take Vrabel, but I do not want a defensive minded head coach. I certainly do not want a guy who has been a head coach multiple times and failed like Spagnuolo. I guess in fairness, his second time around was only an interim head coach for a handful of games. But he was awful with the Rams.
Could he be one of those head coaches that failed his first time and then becomes a great head coach his second time around? Maybe. But I don't know if I want the Pats to be the test bed for that theory.
