When Klay Thompson was blocked at the rim by the Raptors' Danny Green in game 6 of the NBA finals, it was clear that something was seriously wrong from the moment he landed awkwardly. You could see from Steph Curry's anguished pounding of the ball into the floor and the ashen looks on the face of fans in the stands of the Oracle Arena, where the Golden State Warriors were grimly hanging on to their title against Toronto. Incredibly, Thompson came back out to shoot – and score – both free throws.
