I also don't think it's the worse reaction they've encountered. In very recent times it's similar to the U21 semi-final, similar to Kerry, similar to Armagh, similar to Dublin O'Byrne Cup - if you were to do a search on here for 'worst ever' it would come up a lot... I have long believed that there is a disconnect between players and supporters at inter-county level especially, all the more so in modern times with the proliferation of social media and online forums, and the increase in time given and actual physical separation from the public. It's obviously a boost when everyone is behind you, it must be a lift. But when you've been called cowards and stupid and useless, I think the thoughts of doing it for the man in the stand aren't to the forefront of your mind. I would see that in club too - appealing to lads to do it for the jersey and what it represents and who it represents doesn't really cut it anymore. It will to some, but I'm not sure it does for the majority of the modern young men. The motivation is more personal, and maybe family.
For me, it's their own pride. Is that dented? That's it. If it is, you want a reaction. If it is, but they are blaming management again, you might get a bit but at the sniff of something going against them, they'll fold and go back to default.
If they've taken it really, really personally, they'll at least go out on the shields, which is all anybody ever wants (sick and all as you'd be of glorious defeats, you'd take it over a limp one).
So in my opinion, the backlash from the supporters will have absolutely no effect, except perhaps on the manager's future as that will probably be reflected by club delegates in time, unless fortunes improve. Hopefully they do.
But they will have none on the majority of the players.
