What has always defined a guard is the ability to pass, dribble and shoot at a high level. Durant can do all of the above. The argument wasn't that he would be a point guard, it was that he can play it, which you agree he can. He also does set up plays, tells people where to go and does very well at creating for his teammates. Passing out of a double team is creating a play.

You demand a double and cause a teammate to open up which you then have the vision and ability to make the pass. He's not a top 5 player just because be can shoot. There are plenty of players who can shoot. Who you guard or don't guard doesn't matter, otherwise Kawhi would be considered every position. Either way, we agree he can play it, which was the point.
