I got a question. So there this one player I drafted in a $120 mil league, I believe his salary was around $5.2 mil. Well this guy was used 10 times ever in an OL, and then I drafted him. His salary went up $16. Not a huge difference but here my question. Does the salary only go down if no one uses him? Like for '08 Joss, if less percentage of people use him, as long as 1 person uses him, his salary will go up?

I believe the price adjustments consider usage across all leagues - open, theme, and progressive. It could be that your guy has been popular in some themes running recently.
