I made a game on challenge mode and became manager of a rookie league team. I did fairly well missing out on the playoffs by one game. However, after that season ended I was promoted to a short season team who was still in the playoffs. I ended up losing the playoffs but challenge mode counted my time with the short season team as a full season. So, for 2017 it looks like I was skipper for two teams at the same time. This caused inflated challenge mode statistics.
