The day Bryson, Dustin, Patrick Reed or another of the top 50 players is assessed this penalty I'll agree the blue blazers are actually going to enforce this equally. As of now this penalty is as suspect as many penalty kicks called by FIFA referees prior to VAR.
Your dreaded “blue blazers” have nothing to do with his event or 99% of the other ones you see on TV. Even at the US Open the timing is primarily left to the PGA Tour officials on site.
Also, most of the top players know when they have to speed up and do. In 2010 at pebble, I was walking with 3 of the best known players out there. We started on 10. When we got to 4, we had fallen behind due to a couple of issues on 2 and 3. The hole was empty. One of the players looked up, said, “we’re behind let’s go” and faster than I could radio in that we were behind they’d hit 3 shots and were off down the fairway.
When they are right behind the group in front, they’ll certainly take more time baecuas there is no where to go.
