i recently had this happen where i got the complaint email with maybe one game lef tin the regular season. I normally assume that there is no need to start these promised kids in the CT, but i did this time to see if I could get the lost points back. I did star tthem in CT and they did get all thier points back and sent me a text saying they were glad i kept my promise.
normally the key is, as rogelio said, keeping the start ratio above 80%,,, if you do that through the regular season, then you wont need to start them in the NT or CT.
Im not sure if i ever tried starting them 20 out of 25 and then not starting them in the 26th game. that would let them fall below 80%, but would they complain since regular season would then be done?
