Naah. You are doing what you accuse PGMOL of - making it more complicated than it has to be to solve a minor problem.
Two challenges at any time. Failed challenge, lose it. Throw-in the last minute, who cares? It can genuinely affect the game and if you don't allow it you will get the same trouble as now: why only decisions that lead directly to a goal? Keep it simple.
OK fair point, note that while typing that I was brainstorming on how best to craft a challenge system with an emphasis on maintaining a natural flow to the match while also limiting match disrupting petty challenges that could disrupt or extend the match in response to BlueHammer85's point.
There's a way to achieve this without sacrificing a manager's ability to challenge anything at any time. Anotherwords, I would make a distinction for the ability to challenge what led to a scored goal after the goal was scored. So if a foul or a corner was given, which led directly to a goal, the manager who's side had the goal scored upon then would be able to challenge a decision that led to the goal, after the goal was scored.
But to be clear, yes I would agree that managers should be allowed to challenge any decision at any time, even if the decision did not lead to goal. But my point is that they would have to be quick about it. Anotherwords, they should only get like 20 or 30 seconds from the time of the non-goal scoring incident to request a review, particularly if it's a missed foul no-call play on and the manager wants a review of the tackle that he thinks should have been a foul. There needs to be a set amount of time that he has to make that request, and also if the play is still going while a challenge is made by the manager, the referee would then have the discretion on when to stop the action to do the review.
So we agree that everything should be allowed to be challenge, but specifically after goals were scored, I am proposing a longer window backward to challenge what led to that goal. Do you agree with that and the part about challenging non-foul no calls with play continuing as a challenge is requested?
I was trying to be mindful of BlueHammer85's comment about possible petty challenges to time waste. As I was thinking about that I would say to you that having only 1 challenge each half would be better than 2 over both halves because that goes directly to BlueHammer85's point. That if managers were given 2 over both halves and they didn't challenge anything they could aggressively delay the end of the match with 2 or possibly more challenges on every little thing just because they can and delay the end to the game. That could lead to undesirable prolonged stoppages to end the match.
By limiting each manager to only 1 guaranteed challenge request per half, that reduces the possibility of what BlueHammer85 was concerned about. I agree that if you win a challenge you should have another opportunity to challenge but it shouldn't be endless as you were suggesting. I would put limits on it, like 3 challenges max per match and perhaps 2 per half max. So I would provide 1 guaranteed challenge per half, if you win a challenge in the 1st half you could challenge something else in that half. Or maybe you could save it for another possible challenge in the 2nd half, if lets say you lose a challenge in the 2nd half, but had already won 1 in the first half. Maybe you could have a 3rd. I would be OK with that but we can't have endless challenges even if you keep winning them.
We really need to put an emphasis on limiting stoppages and only using it as a means to overturn the rare howler. But I agree with you about being able to challenge anything, anything at all, even decisions that aren't covered by VAR like corner kick / goal kick decision or throw-ins. But on the other hand, in my view, we really should limit the amount of possible challenges and possible stoppage to ensure that managers are very strategic about when to request a challenge. It's something that ideally should only happen rarely. If you give managers too many opportunities to challenge, the match will lose flow and there will be too many stoppages.
I'm just throwing out ideas here whilst brainstorming on how I would craft the system. But I am just thinking out loud, I want to hear your input as well and what you agree or disagree about my proposal. I am not saying my design of it is the be all end all, but one thing is clear, PGMOL and FIFA need help crafting their system after their debacle of VAR. PGMOL and FIFA cannot be trusted to design a challenge system that best serves the sport. So I am putting my thoughts on there on how I would craft this system, since it's being talked about and considered to replace VAR.
Whether or not it will replace VAR is unclear at this point, but at the very least we should talk about it here and discuss all the limits and parameters of how it would work best. I think the idea of allowing corner kick / goal kick decisions or throw-ins is an important one. And the point about only allowing challenges for goals scored, by the I meant only to be able to challenge any decisions that led to the goal. The manager would also have the ability to challenge a corner kick decision at any time, even before the corner kick. But he would have to be quick to do that, and in the event that he does not challenge in time he should be able to let the corner kick be taken, and if the ball is cleared out then he wouldn't have to use a challenge.
The idea of this caveat is to avoid unnecessary stoppages that do not change the trajectory of the match. So to be clear, the manager could challenge for corner kick / goal kick or throw-in decision at any time right then and there. But the idea is to keep the game flowing and making managers very mindful of when to use a challenge. But allowing them to challenge what led to a goal after the fact would work into the calculus of the strategy of the manager on deciding what to challenge.
These parameters would lead to limited disruptions of the flow of the match and reduce the amount of petty challenges late in a match.
