So, maybe this was known to others and it's just new to me, but I think there must be a built in "level up" in likelihood of leaving at the 900 rating point.
My back-up SF, Cesar Martin, just ticked over into the 900s and shot from "Likely Staying" to "On the Fence". He hasn't had any huge games, and hasn't had an increase in stats/minutes, so I can only assume that part of the Draft Big Board logic has to solely do with Ratings rather than perfomance (which it probably should), but that 900 rating mark seems to be one of them.
I'd be curious to know if others have experienced the same, or maybe I'm missing something.
