It outlines the obvious that last year was bad. Outside of last year I'd urge you to look away everything from total defense to S&P to FEI. They range anywhere from average to good to really good for the most part.
It's gotten worse and there's no doubt about it. But one season is not the sample size. If you actually read the post, the whole point would be that you could get fired when only one of your 4 years is bad. And that wouldn't be appealing to someone looking at it as a harder place to recruit and pay below market value.
Fans always want to fire someone for one season. Not only does that not happen much in CFB in general, it definitely doesn't happen on a wide scale when your worst year is an outlier.
That being said anything is justifiable at this point. It's been long enough and anything further would indicate a bad trend and a lack of corrections and ability. So it wouldn't be surprising to see it despite the "Kalani's buddy" idiots.
