The elite teams are able to do that. It's common knowledge in the NBA that general offense only takes you so far. The teams that win titles - or at least compete for them - are the ones who have guys who can go and get buckets down the stretch. Golden State has Steph Curry. Obviously, Cleveland has LeBron. Even San Antonio - probably the best ball-movement oriented team in the league - has Tim Duncan, Tony Parker and Manu Ginobli.
It's a skill that not many have, and one that can launch Hayward even further up the ladder if he can acquire it.
