I'd say Okoro's athleticism most reminds me of James Augustine as far as any recent Illini big. If he was in an all out sprint, he could beat just about anyone down the floor. Augustine's basketball skills were a little more advanced (although I never saw him as a HS junior) but it seems like everyone marveled at JA's hands, agility, and general lack of awkwardness for someone so big from the get go.
I stopped at Pontiac on the way back to the burbs from Pekin yesterday and watched Currie play...they've got a couple long, bouncy string bean types who impressed me with how hard they play (I didn't even grab a program, so don't know their names). I was also impressed with how Currie was coached....with my real only knowledge of their program being around Cliff Alexander, they are far from a roll the ball out and let them play type of team. And I will admit, I was shocked when their coach told Marquise Walker to take a seat in a little more colorful language after he talked back to him in the huddle.
