rugby seems to manage it fairly well with stopping it for anything that needs set up or a "word or two" and it doesn't need to go all the way down the tree at once as it could trickle down from the top
Not really. Most of my friends are rugby men and I occasionally get into conversations of the length of in-play timings of the two sports. Sadly I carry around a Sunday Times cutting complaining about the in-play timing of first class club rugby for a particular weekend, think it was c. 2019, so ball in play:
Bath v London Irish 33m 59 secs
Bristol v Saracens 27m 06s
Exeter v Leicester 29m 15s
Harlequins v Sale 24m 58s
N'hampton v Wasps23m 32s
Worcester v Glous 32m 17s
I rest my case M'lud.
