I don't like Vrabel and while I like Flores, a lot of information came out about how he was treating people and I don't think it works in the modern day NFL. But, maybe he has learned since then because I really love the aggressive defenses he puts on the field.
Anyway, Ben Johnson or Slowlik are probably at the top of every list but I do like Aaron Glenn and Kliff Kingsbury as options if we can't get the top guys. Kingsbury concerns me because he was fired in Arizona after going 4-12, but he did a great job there before then and has done a good job with Jayden Daniels in Washington.
