I am thinking Cliff Robinson as a comparison for Isaac.
Cliff Robinson was 6-10 220lbs. Size & athleticism. A terrific defender. Super versatile defensively. He could defend all 3 frontcourt positions and even some two guards. A solid scorer but more comfortable as a 3rd option than a #1 or #2 guy. He was a 20ppg for a few years but seemed happier as a 15-17ppg guy. A bit streaky to be the main scorer. Too big for SFs to handle. To skilled and quick for PFs. A good rebounding SF but below average rebounding PF.
Isaac looks to be a more natural rebounder than Uncle Cliffy. Other than that, I think they share many of the same characteristics.
