I think it would be useful to have the ability to lock in a player for a game that has already been played then EXCLUDE the rest of those players from that game allowing you to be able to generate a new lineup with a player thats played already (if that makes sense). Example would be Cavs vs. Mavs at 3pm and I have Lebron. Now for the 7pm games I would like to have updated projections with having Lebron locked in.
