this is what happens naturally when teams that have a superstar are nervous and need a bucket, they revert to hero ball and settle for bad shots, westbrook turns into westbrick, curry cant hit his shots, durant cant hit his shots, klay cant hit his open shots, its the downside of being such a good scorer normally, they expect to do it in high stress scenarios with the defense up the ass
cleveland in game 7 were nervous and also turned into that mode, so they both had a few minutes in that game with no scoring and wasting chances to win
