This is really good and answers a lot of questions I had re: whether this change would result in “onside” goals under the current system being ruled out by on field decision (though whether this decision would change if officials knew their call might be the decider is unclear) https://twitter.com/dalejohnsonespn/status/1334111759024623616
In other words, now refs don’t *have* to flag the narrow ones; with margin of error, they would have more of an onus to make the call—presumably following the old “benefit of the doubt goes to the attacker, but who knows”
My actual issue w VAR offside calls’ narrow margins is that players themselves can’t see those margins in real time, so we’re judging them off things they literally can’t adhere to with their eyesight—which punishes attackers milliseconds more alert than defenders in practice.
(Basically, I agree w Johnson that frame rate issues mean sometimes—not always—the correct frame won’t exist to judge using these margins, I just think it affects everyone so isn’t as unfair as it seems; my issue is that tech itself is unfair to players—a minority view I think!)
Here's where I wrote about a number of issues people have with VAR, including the decrease in open play goals allowed due to tight offside decisions (and I cite Dale Johnson a lot, who you should be following). https://liverpooloffside.sbnation.com/2020/11/30/21750324/var-issues-rules-officiating-epl-ifab-liverpool-offside-penalties-celebrations
I also follow @Nico_OMorales in combating the idea of the absolute — in this case, whether these margins given various constraints are "correct" in a sense & whether they're fair/what we want from the game. From player interviews, I gather it's very much not what they want.
Here's the article I refer to in the last tweet: https://nico-omorales.medium.com/the-decision-has-disappeared-a-metaphysical-critique-of-var-e9ea605a9f37
