Did you watch the clips?!? He didn't go to the rim very often, but when he did, he threw one down with authority. I don't think Cam dunked the ball even once this year. Cam has a solid build that handled a lot of contact. Koby has a slighter build which is probably why he doesn't go into the paint much. Might do him some good to hit the weight room during the off season so that he can broaden his game.
Don't get me wrong, I love Cam's game. He was very crafty and good scorer from anywhere on the floor, but scoring over a defender was definitely not his game. Brea seems to spend most of the time beyond the arc, but did show some mid range game and a couple of athletic plays at the rim, including a couple of nice weakside blocks.
I thought he looked more athletic than Cam. Not saying he'll be a better player. Spencer was special. His intensity is unmatched. He made up for his lack of athleticism by being so crafty on both ends of the floor. He'd jump into passing lanes, similar to Nadav back in the day. He used misdirection to shake his defender and make just enough space to kiss it off the glass.
The fact is Cam used up his eligibility, and Brea looks like a nice fit. He's probably more of a Jordan Hawkins "type" player than Cam Spencer, and Hurley found a way to win the NC with both.
