Sure, but the circumstances of the other 4-0 team are universes apart.
How much of the "good" that he has done that's right in your blinders?
K2 may not be BB, but given what the Cardinals have had...in its entirety of a franchise, he has been pretty decent so far.
Remember, he took over one of the worst teams in existence and one of, if not the most pathetic franchise in existence, and has improved every year. From someone who has never had ANY NFL coaching experience, ever. I am fairly certain he is the only one to ever do so.
That's pretty damn impressive regardless of anything else. I think the players were just as easily as fault as coaches for the collapse last year and I think they know it. But you know what? Maybe it was a good thing. This year is a different mentality that wouldn't have been sharpened if not for the collapse last year. As long as there is growth, I'm fine with it.
Enjoy the moment while it lasts, we've only had a few of em.
