just to be clear, is that mean he leaks the vods to other team or what?
teams will usually record their pov during scrims, to review and go over after prac. leaking vods would mean basically sending a clip of the scrim or telling the other team what the scrim partner did during the scrim. for example, the comp they used, what they like to do during pistols or ecos, stuff that can be easily anti-strated and would benefit the other team in matches.
