As a part time plastic rugby watcher, seems to me they’ve fiddled with it a little much. They had something that worked but I guess the temptation is always to build on it, can’t leave anything alone. Maybe they share that with football’s authorities.
Now using it for the noble purpose of judging tackles, limiting head contact, with all the discussion around concussions and issues later in life. Perfectly understandable. But it’s brought their VAR into very subjective and contextual matters and gotten very messy.
How high was the tackler and how well does he wrap arms. how low was the runner, what’s the intent, where’s the ball, slow it all down and run it back and forth 10 times. 5 pundits between them come up with 5 different conclusions. Nobody’s really any the wiser.
