I think the generational aspect is one that doesn't get considered enough. My dad's idea of a Saturday was lots of beer / football / some fights but he was going in the 70's/80's mostly and can probably count the times he's been to St Mary's on his hands with fingers spare. So he was in the pub with his friends before, during and after the games - it builds that connection in the group of people. Mine is a burger, a quick pint (or more likely a coffee) and the match - maybe with my brother in law when he's not at sea but it's not an all day thing and I have no desire to get drunk on my own. My eldest (21M) doesn't drink at all, my youngest (19F) does but it's one or two at most and the tribal nature of football doesn't resonate with them but they will watch it if it's on the tv (ie I'm watching it) and almost all their entertainment is from some element of streaming service. So I think the disconnect will increase as more of the fan base is younger and more used to interacting with the internet over people in person, especially as they can pretty much now watch any football game they want from anywhere in the world. Of course that is a bit of generalisation but it wouldn't surprise me if football crowds in general have got quieter over the last few years.
It was good - I also liked his yellow card at the last one too, especially as from my side of the ground his white shoes / dark clothes combo just means I see a pair of shoes wandering around in a sea of dark colours... (though that could just be age related blindness creeping in) The in stadium entertainment always feels a bit forced. The interactive team sheet a couple of weeks back was a damp squib for example. I'd rather they tried to make the half time a chance for the kids to cement their football match experience and get locked in as fans instead of watching a few partially drunk blokes attempt to kick a ball and / or knock each other over.
