I'm not buying my roster yet. Gonna wait until the start date comes and see who's still hot.
And about the roster changes:
Roster moves may be made starting 7 PM ET on Wednesday until the roster-lock deadline of 7:00 PM ET on the following Monday, but any transaction goes into effect that Monday. So, all contestants stick with the roster they have at the Monday deadline for an entire week. Rosters will lock for 48 hours after the 7 PM ET deadline on Monday and open again at 7 PM ET on Wednesday. Be sure to check
