Onuaku started shooting that way at Louisville in college, and it brought him success. This feature from the Sporting News talked about the success he has had with it and the resistance that the form still faces, despite a sustained track record of success.
It has been working, to a degree, for Onuaku in the D-League as well.

Onuaku's willingness to turn to this type of device to try and improve his form is admirable in its own right. If players like DeAndre Jordan and Dwight Howard got over themselves for how they look and tried this, it might actually improve their percentage, give them more points, and improve their teams. Pride about aesthetics in a professional setting is overrated.
Good on the rook, and hey, he made both.
