It's a great point of discussion.
I think the journey was largely sentenced to 'bedding in' when we aggressively persued the youth signing policy. There is no doubt we have ended up having to play Bergvall and Gray far far more than we wanted to in terms of senior development, as for Moore he would've been in U-21s with the occasional appearance on the bench.
It is somewhat sad that the club chose Postecoglu to spearheads this 'root and branch' change within the club. There's a huge argument for saying they should've gone all out and got someone like Amorim - young, charming, defiant, sure of himself - and perhaps it would've been different. He would most certainly have given us a 'figure' to believe in. Instead, we went with Ange. I suspect choice dictated that to an extent.
Next season we will see players like Bergvall and Deki ascend fully to leaders. Gray will be a 'bigger' presence. We will finally see the scratch notes of a narrative imagined yet haphazardly executed start to blossom as the young players gel more and more under the leadership of (hopefully) a younger, more dynamic manager. That's the hope. Ange has done his time, and there is no more he can do/not do.
You raised 2019 so I have to go there again. First off, EVERYTHING you say about it is bang-on. I will add that we were on the doorstep of doing the impossible -winning the biggest club prize in world football- without blood or VC money. What Poch did inside and outside the club was beyond incredible, and as someone who was a regular during the Burky years, I can say I never felt as much pride in who we were as during those years with him. I shed many tears that night in Madrid; a small piece of my footballing me broke. I shed further tears when he was sacked, because I knew we'd never have such an opportunity again in terms of the narrative you talked about. A bigger piece of my footballing me broke that night, and was further bruised by the appt the next day.
Everyone defines success differently. For some it's trophies only, for others it's more (or less depending on perspective). I never felt more pride in this club than during those 2016/17/18/19 seasons. That final season at the Lane was incredible. We were beautiful and the story was poetry in motion, led by a poet who created the verse we had craved and needed (Jol probably got closest before him during ENIC's time, he could modulate with us in that way albeithe was also a bit of a grifter).
