i think the difference is that theres some qualities a player has that you will only see in ranked. like fragging power. a dude may drop 35 in ranked every game and then drop 8 every game in pro matches (mazin in stage 1 vs him in ranked a few months back).
but things like mind for the game/game sense (is that and mine for the game the same thing?), movement, comms, etc, are stuff that dont change based on the environment youre in.
those qualities are things that people highlight in sinatraa's gameplay all the time.
when he played pro (and when he genuinely tries, i.e. the NRG trials) he genuinely was a very good rifler, and was willing to play whatever (according to chet who just put him on iso on haven and he never questioned it) and his decision making was on point. FNS and dapr have both described him as a literal perfect teammate, one who will frag out for you nonstop, rarely have a bad match, and almost never baited (while almost exclusively rifling).
