When Shelden Williams was a freshman his offensive talent was extremely low his frosh year at Duke. He traveled nearly every time he got the ball. I assume he was still more talented than Obekpa, never having seen him play, based on all accounts, since Shelden averaged 8 points his frosh year. That said, Shelden was a beast rebounder/shot blocker. By his senior year, he averaged 19 a game and was an offensive force in college...of course until his offensive deficiencies were totally exposed in the NBA. That said, just using him as an example of how a top defensive player that is EXTREMELY raw offensively can make an impact immediately, and also can become quite talented offensively with the right coaching. Obekpa would be a great signing!
