The 2 former CAVS point guards that he resembles from my perspective are Kevin Johnson and Terrel Brandon. The fact that he is 12th most impactful rookie at this stage demonstrates good scouting by the CAVS.
CPJ does a much better job passing the ball than Sexton. Has way better vision and can orchestrate the offense. The other parts yes agreed.Porter reminds me of Collin Sexton; 6'2", super quick, big vertical jump, weak outside shot but does a great job attacking the rim.
