I agree with most of what you said, but Vrabel is not so much my favorite choice, but the best example of a new HC that would not be a play caller and knows how to create a culture of hard hitting, hard workers.
Regarding Flores, I think he’s learned from the bad press of him being “mean” to Tua, but he also had an owner that picked a QB he didn’t want and expected him to win big now. That seems the opposite of Saints ownership.
I love Johnson, Slowick, and Glenn - but Glenn is not far enough away from what the Saints need to get away from right now, because that would mean Loomis is staying and having the same level of control as with Allen.
I love Kingsbury as an OC, but I don’t think he’s ever going to be a good HC. JMHO,
