Saints are flying Kafka and Weaver in for 2nd interviews [Interviews completed]

I have never heard a GM, coach, or owner say any NFL HC is “bad”. It’s extremely unprofessional.
You mean like Payton did about his predecessor in Denver? Don't have to use the exact word "bad" to say you think someone is bad at what they do.

There is a mechanism to suggest they don’t think he is good enough. It is firing them or not renewing their contract…
So you haven't heard any current or former owners, GM's or coaches say anything negative about McCarthy.

Fired by Green Bay. (not good enough)
Hired by Dallas. (good enough)
Dallas tried to bring him back, but they couldn't agree on new contract. (good enough to try to get back, but not good enough to agree to all terms)

I've not seen or heard anything to suggest the other 30 NFL teams. that aren't Green Bay or Dallas, share your opinion that McCarthy is not a "good enough" head coach.
