On Monday night, Houston Rockets‘ center Chinanu Onuaku debuted his underhand free throws during his team's game against the Phoenix Suns.

Many were surprised that he shot it “granny style” and at the same time impressed as he made both of his attempts to the delight of the home crowd and his teammates sitting on their bench,

During his college career, the 20-year-old Louisville product improved by almost 13%, from 46.7% on his freshman year to 59.6% the year after he changed his shooting form.

With the success he's had with his new style, many have been wondering why some of the poor free-throw shooters in the league, like Detroit Pistons‘ center Andre Drummond, have not tried it yet. Apparently, the master of the underhand shot, Rick Barry, has already offered to help him out with it, but he was not receptive to him and declined.

Pistons' head coach Stan Van Gundy recently admitted that the team has tried all techniques possible to improve Drummond's percentage but also made it clear that expectations on him should remain realistic.

“Everything was considered, but he wasn't as receptive. You don't really want to do things guys aren't receptive to.

“He's made a significant improvement from last year. The guy's up 10 percent. That's a huge improvement. That's certainly nowhere near where you want it. You certainly don't want it below 50, but I think expecting him to go from 35 last year to 60 right away is probably an unrealistic expectation.”

“People have done it, tried it. People have tried everything. Tristan Thompson switched hands for God's sakes. I know Rick Barry's talked to me a couple times. He's in disbelief more guys don't do it.”

After hearing Van Gundy's statement about his All-Star center, it appears he is already content at this point with the improvement Drummond has shown and wants to prioritize how he wants to work on it over what others think is the right thing to do.

This season, Drummond has been shooting a career-best 44.7 percent from the free-throw line and has been getting fouled less compared to last year. If the trend continues and he shows he can sustain the improvement he's showing, it gives less reason for him to change his form and just stick to what the team is doing now to help him improve as it proves that it is working.
