His tweet has no mentions of Analytics department which you added and his initial tweet is pretty misleading. Not having a dedicated scout for other players is not exclusive to Lakers. Many teams don't. A GM and others in FO usually handle that situation.
Edit: And coaching staffs also have scouts that do reports on other players for gameplan, which we have. They showed it many times last season during the behind the scenes show.
brehs really out here pretending the Lakers are operating with half the staff of other NBA teams
