Francisco and Bossi on Rabb

Here's ESPN's Joel Francisco after recently viewing Ivan Rabb:

Best California Prospect
Ivan Raab (Oakland/Bishop O'Dowd)
2015, PF, 6-8, 195
Status: Claims offers from Arizona and California, with interest from North Carolina, Ohio State, Oregon and Oregon State among others
Raab is an outstanding prospect for the elite high-major level. Blessed with very long arms, soft hands and quick leaping ability, his upside is immense. He converted buckets over his left shoulder and threw down a number of rim-rattling dunks as well. He struggled scoring through contact at times and needs to continue to polish his footwork (he traveled many times while finishing), but overall he is much further along than Arizona frosh Brandon Ashley at the same stage.

Plus, Eric Bossi checks in:

Rabb was outstanding at the Tarkanian Classic. The power forward from Oakland (Calif.) Bishop O'Dowd dominated in the two games we watched. He's long, lean, quick off the floor, has great hands and can run. Given that he's 15 years old, it's no surprise that Rabb's offense is still developing, but it isn't exactly raw. He can face and hit 15-footers, spin to either shoulder for buckets, and he looks comfortable setting up to operate on either side of the lane. Time should allow him to add strength and continue to be more assertive as a rebounder and shot blocker. Arizona, California, UCLA, UNLV, North Carolina and many more are tracking his early progress closely.
