Cro2 team, my apologies if posting this violates any terms of the contest.
No, you basically answered what I would say as well.
We are giving you questions, sometimes a week in advance and that creates logistical problems. We are doing research when posting them but new info is getting available by the day. It is your decision to decide when will you enter your questions and do as much research as you wish to do. Of course that person that waits until last hour will have advantage. That advantage will be bigger on some weeks and smaller on others. We try to create questions in a way that new news will not invalidate them and this question is a good example of that. Even if all three are injured and nobody from Neymar, Messi and Mbappe plays a minute there is still a winning answer and question will stand. We are sometimes giving you info in the question to help casuals and make questions more interesting but that info isn't official and could be old by the time questions go live. For instance I was writing my half of questions on Sunday morning and deadline is 6 pm Tuesday. That is over 50 hours of new information, quite a lot in these modern times.
Rule of thumb, if there is an answer covering outcome of the match, question stands and point goes only to persons that selected it. Question will be removed only if we screw in a way that nobody can get a point, or "force majour" happens. For instance Arsenal game gets delayed because of Airline strikes and game isn't played before Sunday 10PM. We have to remove that question since we don't know what would have been the line up.
I even warned you guys about Tennis question this week, it could be settled before the deadline and I know I am waiting before posting my answers for this round. Not last minute but last couple of hours.
There will never be a possibility to edit answers, that would solve some problems but it would also create many new problems and ones that can have much greater consequences on competition as a whole.
