There are quite a few things that IT is better than Kyrie at actually, including defensive effort, playing at a faster pace without turning the ball over, and getting to the free throw line. IT has better passing skills than Kyrie as well.
he may be better at defensive effort but he is worse at actual defense.
IT is a somewhat better team player than Kyrie but not as good an ISO scorer or pure shooter, particularly in pressure situations where fouls are not getting called.
