I totally agree with this pick. I think Cassiday is the best on ball defender in the state hands down. I have seen him guard all 5 positions this year. He can guard on the perimeter against smaller guards. He can slide down to the post to guard bigger players. He rebounds, contests shots, and is usually in good defensive position on or off the ball.
He did a nice job at times against 2 of the best players in the state in Christenson and Chu, which is extremely difficult to do.
I think talent wise, he is top 5-7 in the state. But, he was injured during the season, and he missed a lot of preseason. Punahou was a far different team when he wasn't playing.
