Nemanja Blazic knows his way around a basketball. He's posted videos to YouTube of himself schooling people on an outdoor court, as well as spinning a ball on a toothbrush while brushing his teeth. But in a new video, Blazic puts a scholarly spin on his usual spin. He can be seen writing the word, "Tricky," which is part of his YouTube channel's name, on a sheet of paper, while a basketball stays perched atop it, spinning all the while. Very impressive. Totally baller.
