This is very straightforward: you have to decide before the the next roster deadline after the trade. This is not convenient if the roster deadline is 11:59 this evening and the trade goes down at 11:58.

However, fortunately for all of us, the roster deadline is 11:59 PDT this evening, but the trade deadline is 6:00 PM EDT, which means 3:00 here. So the worst-case scenario is an EFL manager would have nearly 8 hours to a) discover one of his players could be traded, and b) decide whether to trade him.

I hope this is the same answer as we came to yesterday.
