and this is where we will disagree, we may have already on another thread, in the years i played and in the years ive managed clubs since, ive never met or heard anyone opening talk about deliberately collapsing a scrum, hell we have strict protocols for someone to call out if they feel theyre in a dangerous position and it may collapse
yes, lots of old tricks for making things difficult for the other scrum, angles and binds, hell, plenty of people back in the 90's would admit to throwing an uppercut....but never collapsing, everyone knows its next level dangerous
