My take on the WMU thing is, replay is completely broken.
It started out with the sole purpose to fix "clear and obvious " mistakes/errors. Things like players stepping out of bounds or not, or obvious clock/procedural errors
I don't know what they are doing now, but saying that it was clear that there was 00:00.04 or some other absurd fractional amount of time left when a player made contact with the ball is so far outside of what replay officiating was designed to do.
That said, I don't know what the answer is. If there was 3 seconds left then the replay officials should be able to overturn an obvious error where the tumekeeper let the clock run and said the game was over
This is just ridiculous, and it definitely calls the integrity of the game into question.
