The game didn't flow as well either by adding Offsides. I'm sure a lot of purist whined about it when it first got instituted. But we grew used to it. And now we will grow used to innovations that reduces the error rate in that rule.Anyone that thinks the spectacle is better for having var is deluded. More accurate, for sure, but the game does not flow as well at all. Thats clear.
A change in rules is completely different to a change in structure to the officiating.
As long as people are making decisions live, there is no delay, irrespective of the decision or the rule. Offside rule or no offside rule.
A ruling that is made 1 minute or 2 minutes later is a fundamental change and disrupts the game.
Not for the good
Also later decisions are not unique. Playing advantage is a type of delayed decision. We got used to that too.
The only thing constant about the rule of football is change.
Most American fans are already used to delayed celebrations. The technology will get faster and decisions will take 1-5 seconds instead of 20-30 seconds.
We will all be better for the accuracy. Except for the conspiracy theorists that is :)
