The original question was whether overtime minutes in an exhibition game affect improvement. If it does, it is a miniscule amount. One time I forgot to schedule exhibition games, and I panicked a little, thinking I just missed out on an opportunity to improve. I was surprised to see that all my players had improved. They might not have improved as much as they would have had I scheduled exhibition games, but if that's the case, the difference was pretty minor. So if we're answering the question about a 5 minute overtime period, I'm just saying I wouldn't get that excited about all the additional playing time & improvement opportunity that could have generated, if any.
