The best guys I've ever had were all high mileage guys.
If you know what you are doing as a coach, then it makes sense that the more you train, the better you'll be as a runner.
I must disagree; I think there's some fallacious thinking here.
"Great runners run high mileage, therefore high mileage makes you great."
Or
"If being really good and high mileage are correlated, then the second causes the first."
Not necessarily true, and one of the toughest things in running to get to the bottom of. Great distance runners can handle high mileage, so on 100mpw they get better and not injured. That's not to say that the average runner would benefit from or be able to handle 100 mpw. Maybe they would run their best off of 75, because they'd get too tired or injured at 100. Maybe they'll be able to handle 100 in two years, but not now.
Again, that second statement is definitely false if read literally. As I said before, if that were true, everyone would train all-out 24 hours a day and everyone would be unbeatable.
Recovery is crucial in the training process. The more you train, the less recovery you get. The key to improving is balancing training and recovery. I'm not against 100 mile weeks at all, but more is not automatically better.
