Well let's see
Coaching:
Gibson, Gibson and Gibson. Hore defended him and ignored the 2017 review to sack Gibson. The Tahs were a basket case on the field despite experienced players but Hore kept re-signing him and let him run the team like a bunch of headless chooks.

Well, I certainly know how to press your buttons.
Gibson's main contract was prior to Hore arriving yet you seem to put Hore as the chief architect for everything Gibson did. Could it be that the assistant coach NSWRU had spent 3 years grooming as an assistant to take over from Cheika was their darling and they're the ones who were pushing to keep him?
Recruitment of young players finally started happening well in 2019 (Hore's last year). That's when we signed Harrison, Bell, Ramm, Donaldson etc. Prior to that we'd dip our toes in with young players on contracts and largely they were guys that never went anywhere. I'm looking back well before Hore's tenure to question when this was last done at all well.
You seem to assume Hore was given carte blanche to do whatever he wanted within NSW Rugby. History before and after suggests this is pretty unlikely.
Or if I asked about Roger Davis would you say exactly the same things?
It's literally not possible for each of the key players in the saga to be wholly responsible for every aspect of the situation.
