I see only four Scotland players took a knee pre-match.

I wasn't aware of that until I read your post.

Majorly disappointing from my perspective.

Not all of the English boys did it either, nor the Welsh nor the Irish. There isn't formal guidance on it like in fitba. So not doing it isn't a signifier of any particular  point of view.

I'll row it back a bit (only a bit) as I've since learned from an ex-pupil of yours that the Scotland team had zero idea the England boys were going to do it and had to react spontaneously. You'd still imagine they'd have the sentience to give the guy next to them a nudge of course.

 
I'll bow to J's knowledge on that, but I 'd say two things.

First, Scottish rugby should have had the nous to say similar in the press.  They tweeted numerous times about Scotland's victory so could have alluded to the fact that nothing had been agreed regarding taking the knee. 

Second, the players play a team sport.  They should have followed their teammates who did take the knee.
