That's a far cry from the OP, in my opinion. Of course I'd want to know if there was recent history between two teams, because that will be relevant to how you will respond to 'the history' issue.
Nobody said anything about a 'bubble'. Every game is different of course, and we are there to respond to all manner of events that may occur during a game.
Let me provide this supposition: suppose your JUCO "big rivalry" had turned into a big nothingburger, that the teams played a great game with no ill effects whatsoever? Had you prepared yourselves to umpire something completely different, or did you let that information influence how you ran the game?
We've all had those 'meaningless' games where major crap storms developed out of nowhere. So we respond to that as it happens, but sometimes our expectations are of a sleepy, quiet game,and we can end up overwhelmed when things don't go quite according to expectations. The opposite is also true, when the anticipated storm turns out to be smooth as silk.
I worked a college game this season where there was 'history' between the teams, and also some bad blood between the manager of Team A and my partner. You know what we got? An incredibly quiet, 5-3 game where Team B won. Absolutely nothing rocked the boat. Sure, it was good that I had been informed of the history beforehand, but had I been working the game and influenced (in a bad way) based on the history, I'd have come off looking like a bona fide red ass. Just umpire the game you have.
