Coach B,
I agree with a great deal of what you said.
I would put a lot of emphasis on the culture and the expectations in terms of performance and work ethic that can take otherwise fairly average kids under 4:30.
Some people knock Joe Newton for pushing his kids too far, but I agree to a great extent with his point that most of these kids aren't going to compete after college so why not push them to achieve while they are involved. I've had too many athletes with very modest talents decide to get serious about their training on a consistent basis and go under 4:30. Several of these kids never ran faster than 17:## in XC and never ran faster than 0:56 in the 400.
I just had this talk with my team this afternoon. Most of them used the horrible conditions recently to take days completely off. While a couple days off isn't going to kill their chances of running well, they attitude that taking days off because conditions are tough will. Everyone can find what seems to be a valid excuse, then there are those people who just find a way to get it done. The same is true in business and in life.
It's a mindset. I've got a quote on my wall that reads
==============================
"The Secret to Success"
Work harder, more consistently than anyone else, ensuring that you commit everything you have - physically, mentally, technically, and tactically - to every training, recovery, and competition experience
=============================
Too many want to explain away getting beat by saying everyone that beat them is more talented. In general that's a cop out. More talented people can get beat by less talented people that out-work them.
Until you've fully committed over an extended period of time you shouldn't ever blame a loss on a lack of talent.
Why to most guys top out in the 4:40-4:50 range? Because they don't want to do the off-season work required to significantly change their physiology over the period of several years.
