For those that really like Isaac, what does he do besides block shots that Jerebko doesnt already do for this team?
Aside from being somewhat longer (with potential to grow more), Isaac looks like a much more versatile scorer. He's aggressive to the rim and gets to the line at a much higher rate than Jerebko ever has (even in his days in the Italian League) and makes his free throws. Like JJ he's got solid jump-shot mechanics. Overall, he should be a more prolific scorer, though, because he should be able to score in more ways. He's a pretty smart passer as well.
He's a more aggressive rebounder on both ends. JJ is a good rebounder, but Isaac should be distinct step up from that. In addition to his length, he's got very good, sticky hands, like Sully had, where if he can reach the ball, he usually hauls it in.
