Two of those guys got delisted without anyone picking them up. It's not like they were banging the door down. Voss is also a medium forward competing with Stringer / Langford not a KPF height or playstyle.
Could they have played? Sure. Is it some kind of grievous offence that they didn't such that it's a checkmark against Scott? No one but you seems to think so.
I don't see it as a 'grievous offence' - more that if they did play, then the 'we're so young' excuse would hold a little more weight.
And I don't think it's a mark against Scott - but I'd personally be annoyed if he played Weideman over Baldwin in 2024, for example.
