Let's remember that these Leadbetters, Harmons, McLeans, etc. have immense demands on their time. They have devoted their lives to teaching golfers at the highest levels of the game. They have to attend at the very minimum the majors, WGC events, and a few other select big-name tournaments. They often teach on not only the PGA Tour but also the LPGA, Champions, and sometimes European tours. In addition to traveling to and from those events, dealing with their players nagging them, and writing/filming instruction material, they have to make time to teach everyday hacks.
After all of this, I would not expect them to be competitive golfers. They've played all they can play, and now they teach. They literally have close to zero time to tune up their own games, much less play in tournaments. I would expect these big-name instructors to at least have decent swings, but anything above and beyond that just isn't a practical demand of them.
