I listened to tons of podcasts, and read lots of stuff online (including on here), about how he was the perfect fit...
Hindsight is always 20/20 vision.
He was the perfect fit for this club the way it behaves. I certainly said that. We are patently not set-up to take risks with major money signings, and we are not a club who wants to have a strong personality/presence as manager/head coach. The whole concept of Thomas Frank was that is a very strong coach with regards to tactical flexibility both through a season and in-game, that he can make very good use of a squad, that he can improve players significantly, and that he can develop young talent. Add to that the only big question -could he himself step up to the next level as a coach with a club like this and merge his natural pragmatism with a more consistently front-foot progressive style, and on all levels it matched where Lange and (at that point) Levy had this club.
We can go about deconstructing the above in a wider discussion, and I believe your wider point is that even with all that said, a season is not a fair period of evaluation.
I am merely looking for progress in the directions I would like to see them, most notably in the style of play. I have resigned myself to the potential fact that TF's 'endgame' in that regard is a stronger, more efficient version of what he deployed at Brentford, a style I happen to believe has a ceiling and is also not one I like.
I think there is a solid case behind what folks like
@Bishop say about quality, and I also believe the squad is not nearly as bad as some people think.
I think Frank is actually currently being sold out by his immediate superiors. I saw Lange hiding like this last season, and I see him hiding again this season. Last season was certainlty more complicated as Munn took some sort of weird 'ownership' over Ange and that made things tricky. But this season I see no excuse.
I am actually very sympathetic to Frank right now, more so in the last 24 hours than ever.
