I have just came across this thread but personally doubt his abilities. He was completely read but PRX looked to throw away rounds. One tell that PRX were able to capitalise on was the fact that if you saw KJ turret towards B/Street the team was stacked towards A.
Furthermore the pearl they played basically the same Pearl gameplan that Full Sense played but with KJ over Cypher. To me that is not something to glaze and look towards. People will say i am hating but watching the Pearl back these 2 statements can be true. PRX played bad and GE had a okay level gameplan
I personally also do not think he is that good. Because if he was and there was real impact GE would not have been that bad last year. But that clearly is not the case.
