Zach Edey stands at one end of Purdue’s practice court, directly under the basket. He stretches his arms high above the hardwood, and his fingers claw their way into the holes of the net; he doesn’t even have to leave his feet. With his 7-foot-4 frame and 7-foot-7 wingspan, Edey hangs on to the nylon, swinging back and forth, making the feat look like the easiest thing in the world.
