The tour can very easily speed up pace of play by enforcing the rules they have in place and publicly announcing fines to slow players. Start costing these guys $$ and strokes. Some guys take 4 or 5 practice swings, there is no need for that.
Once they get to the ball and pull a club 60 secs is plenty.
They are playing extremely difficult set ups and for millions so some slow play is a given but a lot of it can be trimmed.
