Think it quite bizarre myself.Dyche is a careful talker. The fact that he even “let slip” 2 didn’t respond is relevant and deliberate.
The optional nature of it is necessary for it to work at all, so players voluntarily buy in to it.
But I am surprised anyone wouldn’t respond. If asked why do you think this group of players is underperforming, for a few million quid a year, I think you should probably have an opinion, and if so you should definitely air it for the benefit of all. This isn’t a staff survey at Next/Boots head office about equality and pathways to promotion.
Shades of Brendan Rogers locking envelopes in a draw when he was at Liverpool.
