Koreans have been known to shoot the basketball well, as seen at the Korean Basketball League (KBL).

However, an unconventional way of sinking foul shots has gone viral, with fans noticing a lot of KBL players relying heavily on bank shots, Complex reported.

Some clips of these were posted on social media by a coach named Eric Fawcett, showing some KBL players converting free throws using the bank shot.

"Interesting trend from the Korean Basketball League where a number of players are 80%+ from the free throw line shooting exclusively bank shots," Fawcett's Twitter caption read.

The video clip has garnered over 3.5 million views since being put up. He also explained how he came across the efficient free throw rate, admitting that he was searching for new ways to understand the analytics of American basketball when he spoke to Slate.

"I kind of have this FOMO where I'm scared there will be an offensive concept that's revolutionary going on around the globe and me not knowing about it," Fawcett told the outlet. "So, I'm constantly watching other leagues to see if there is anything innovative I can bring to the college game. So, this time I thought I'd check out Korean basketball."

It didn't take long for someone to associate the viral video with the NBA.

Kirk Goldsberry, an NBA analytics guru, re-posted the video on Instagram and wondered if NBA players could pick up a thing or two from the bank shot strategy.

"Is everything we know about free throw strategy wrong?" Goldsberry wrote in the caption of the video. "I don't think so, but I do believe there is something here for SOME players. Should everyone use the glass all the time for free throws? Again, hell no, but my research over the last 24 hours is suggesting it's worth a look for players who have spent years struggling at the line without breaking through."
