Beverley was making those shots when Kawhi/Danny were also in the game. They gave him those shots b/c they had to collapse when Harden drove to prevent a layup. Their whole offense is designed on driving & kick out to 3 point shooters thus if Harden is getting into the paint & the 3 point shooter are making their shots then it's going to be a long night since it's either layups, dunks, 3s or 2 free throws. It's not like Beverley was making shots off the dribble ala Curry, Boban can guard him out on the 3 point line if they want to run him off the 3 points line & concede layups.
