The Clippers' Jamal Crawford shoots maybe the highest-arching three ball in the game, and has made about 37 percent of them..... About the same as Harden, whose trajectory is close to ideal.
Side note: if you shoot with a high arc on those rigged basketball shooting carnival games, you'll make it. Did this at the Houston Rodeo. I shot 3's in high school with those ball machines, but didn't have to alter my shot. But obviously the closer you got...
