The funny thing about the national football team drama

They only play together a few times a year, so I don't get why there's drama and factionalism.
They don't even need to be close; they should just do their jobs. It's not like they are coworkers seeing each other every single day.
I have no idea why they are acting out like this.
It looks like those guys called the '96 line' are trying to form a clique or something.
Even though they only see each other occasionally throughout the year, those guys seem to be the first ones I've seen trying to create such factions.
