Seems simple to me. If Coach Soles is the problem then these other items must be true:
-The program has gotten better since he left.
-The future GO athletes will run better in college.
-The local athletes in that area will have outperformed his in college, because his were burned out and theirs were not (looking at results).
As a coach who has talked to Doug a few times, and had my butt handed to me many times by him, I would say that it is pretty obvious the program hasn't gotten better, fewer kids will run in college from GO, and that none of the other schools in that area are producing better college runners, even though they don't get blamed for burning them out. Culture may have something to do with it. The kids that went to college and bought into the new culture have done well like the ones listed in previous posts or at least as well as they were doing when they left GO. The ones that didn't or wanted to do something else moved on. My guess is Soles did a great job at making average runners look above average, getting them into colleges. Then the new college coaches didn't do much to improve on their training and some gained 10+ pounds and all of a sudden running got real hard, real quick. I don't know that I would have the stones to blame the person that got me there, but with colleges these days, I'm sure there are kids being taught to blame it on someone else.
As to Doug being a good person, he answered every email I ever sent him. He gave me workouts and ideas, even though I was his direct competitor. Bad dudes don't do that. Anyone that has reached out to him wouldn't classify him as a bad guy. Competitive? Yes. I don't think he denies that though. Keep bashing him if it makes your life better. I doubt he pays much attention to it.
