It's Obvious
S2:E22Aomine thinks that Himuro is good, although the latter had never appeared in a tournament in Japan. Back to the match, Himuro executes a superb fake on Kagami, then smoothly transitions to take a jump shot, to which Kagami and Hyuga cannot react to it. Before the match, Himuro said to Murasakibara that he wants to crush Kagami, and that being brothers with him is getting in his way to be the better basketball player.
