I think the 7s format amplifies the farce, but unless it is illegal under the laws gamesmanship like this will continue.
But even in 15s, how many examples do we see each match? A kicker taking almost the full 90 seconds to get the ball setup just right on the tee for a conversion directly in front of the posts, or the SH "struggling" to get the ball out of the ruck and then very gingerly rolling the ball back along the (inevitable) caterpillar and then taking time to marshal the troops before taking 4.5s after being told to use it, or a team slowly jogging back to the center for a restart, etc., etc... ?
Watching Squidge break down the Red Roses' almost flawless W6N performance, at one point he highlights a sin bin against France (
So can anyone stop the Red Roses? | Women's Six Nations 2022 - about 17m in). Despite France chomping at the bit to go fast at every chance, England managed the game ruthlessly by taking a little extra time everywhere they could and limited the ball-in-play to just 160 seconds across 10 minutes.
And this management is seen as a strength of the team. (And it was still a great match to watch! Roll on October...)
If this specific example spurs WR to call out specific scenarios as time wasting or against the spirit of good sportsmanship and issue targeted law changes or clarifications, I can only hope that they take their time and think things through - rather than rush out a quick fix and leave us to deal with ambiguities in the language and their unintended consequences.
