Probably false...I'm sure other teams train just as hard as they do.
The difference is, they HAVE to believe that they are training harder. That's what binds the worst runners to the best runners to elevate them. If they believe it, if they can dangle that goal in front of their face every day, they will get out the door, pay attention to the details, and train at the level Wetmore needs them to.
I think we take for granted that talented runners are determined. Some aren't. Great coaching, when dealing with immature minds, might be 51% motivation, 49% training theory. The best coaches at the high school and collegiate levels get those kids to trust what they are doing, and use the training group to improve. When you get to your late twenties and on, it's all on you, and you know it. At that level, they have no idea what they really need to do, nor that they might someday regret it if they aren't focused.
So, Wetmore's genius is in his ability to take talent, cultivate it, and navigate both the physical and mental realms of a very individual sport, but retain the team-first focus. The hardest part is starting that culture, once you have it, it can be self-perpetuating. Those kids are right when they say it all started with Goucher and those early teams. Tradition matters for team accomplishments. Most coaches can take the talented individuals to their potential, few can create a program that makes the team more important than the individual as consistently as Colorado has been able to do it.
