either drive since the Suns defenders were all responsible for covering a guy outside the line, or if they tried to help off to protect against a driving Luka he kicked it out. It was fantastically effective, but IMO is kind of ugly ball.
Personally I didnt see much of Celts vs Bucks - I'd guess it was similar with Tatum or Brown having the ball with 3 or 4 teammates outside the 3 line?
