How often do you practice alignment?

This season, I was paying attention to the "warm-up" channel at the majors. Here's a list of players who used an alignment stick during warm-up. PS - These are the best players in the world, but they know how important alignment to the target is that they use an alignment stick to help calibrate their eyes. Rory McIlroy Tony Finau Jordan Spieth Phil Mickelson Rickie Fowler Jason Day Dustin Johnson Billy Horschel Francesco Molinari Patrick Reed Daniel Burger Tiger Woods Beyong Hun An Paul Casey Charles Howell III Matt Wallace Justin Rose Patrick Cantlay
