I guess I can explain how the GE works and maybe it will help you out in understanding. The outcome of the game is decided in the 15 minutes before game time. The path in which the game reaches this outcome to my knowledge is completely random. The game can be back and forth, there can be a few big swings and runs from each team, whatever the case may be. Now as for your game, you definitely had one of the more insane swings I’ve seen, but I have seen it happen before. It is pretty rare to have one as bad as yours but it is what it is. The GE needed to get the outcome that it decided and it took a pretty extreme path, and I guess the substitutions, or lack there of, that you are complaining about was part of that.
I will be surprised if you find someone that knows the exact mechanics behind the timeouts, I’ve played this game since single digit seasons, watching a fair amount of games live and couldn’t give you even an idea of how they work. I just know the GE needs to get to a certain outcome and figure it’s substitutions helps do that.
Lastly, no need to be rude to E.B.W. He was simply countering your points and explaining why and how you lost the game. Your initial post was about timeout mechanics, but you have commented on rosters and other things in which he was referencing.
