I don't know about Breed, but I know Shawn Clement has remarked that he struggled with his game at times, but also decided he didn't care for the lifestyle (TONS and TONS of travel, almost never seeing your family). Certainly it's possible that some of that is just shielding his ego, but it is true it's a rough lifestyle, particularly if you're not in the top half of the money every year.
I have heard PGA Tour pros remark that they'd make awful teachers. Many of them are not even sure how they do what they do. It takes a special skillset to become a teaching pro, and a really special skill set to become a great one. Anyone can learn to read a Trackman, but not everyone can deliver messages in ways that resonate with the student, or pick just the right combination of drills to drive the point home.
