the outcomes aren't predetermined, but the play by play stuff is essentially fluff/filler generated to explain what just happened. each play uses their engine to determine an outcome, and they have to come up with words to reflect the representations they are trying to draw between their sim and real life. their isn't a defensive line breaking through, or an offensive line getting a good first step. it's telling you the results of the sim in steps. it's more like here is the first part of this outcome, here is a little bit more, and this part completes it. it gives you most of the useful information, but it's not really what is happening. there is quite a bit going on for every play, and not all of it is useful information.
halftime adjustments definitely affect the outcome of a game, but sometimes it's not enough. or sometimes we can make adjustments based on biased information, and then we wonder why it didn't work? sometimes its means what we thought we were looking at wasn't actually happening. other times, the universe just liked the other guy that day. which happens in real life as well. sometimes theres no good reason, but app st beat michigan in the big house. for these reasons, and some others, halftime adjustments are rarely going to drastically change the game. and, they shouldn't. unless you can drastically change what players you are putting on the field, the game shouldn't flip on its head because of a couple of adjustments. thats not how it goes for real life either.
with all that said its seems like this jordan guy is the only one who answers these tickets, and who knows how many he gets per day. im not a fan of the new team in charge, but id hate to be the one having to always answer for not just your whole team, but the teams who came before you as well. there are a lot of moving parts here, and i doubt they or anyone else involved through the years ever fully understood all of it. even the guys who write this stuff are going to be finding new things all the time when there are so many factors to be decided to yield an outcome. if you have to take over someone else's stuff.. thats a task and a half. the thing about the fr kicker is wild. if its actually considering that... that changes some things about my understanding of the sim at least.
