If they are going to, they would transfer at the end of the season the same time as players declare for the draft (EE). You have to really **** them off to get them to transfer--you usually get 2-3 emails and see a big drop (10+) in WE before they would actually go. I have had a guy threaten to leave all season (at least 3 emails, maybe 4) and lose 10+ WE but still stay (just to start ******** again the next season).
