100% mate, he infuriated me to the point I stepped off this board, social media and barely could watch Spurs. It was so obvious he need to be gone in November for the latest.
My biggest frustration is the painting of him as "a good coach" who just didn't fit. It was way more than that, his absolute failure to even understand the club he was managing, his failure to give the players basic passing options (triangles), his Porro spam cross directions, how he fudged up Bentancur/Palhinha as a pivot, his failure to improve any of Gray/Bergvall/Udogie/Tel. Said it elsewhere, the only fudging thing that improved in his tenure was set pieces, the thing we had another coach for.
Again, personal experience, I've interviewed people who came from good companies, good projects, passes first glance on CV. When you start to ask "what did you do", "how did you influence strategy", "what impact did you make", you realize they were a passenger, did the part they were told to, but not leaders, not top tier talent, that's how I see Frank.
And like you, I don't think people have fulled grasped what releagtion would have meant for the club's future, at best it would have set us back 5 years or more, the worst-case scenario is levels beyond
