bringing it back.
I think the discussion comes down to what the role of the high school coach is in the greater context of the sport. A returning 10th or 11th grader who slacks on his summer running is going to see the difference when he returns to find himself months behind his teammates. That's a harsh real-world lesson about the value of the work, and I doubt many kids would make that mistake twice. If they do, that's their choice, but it doesn't necessarily make them a "cancer." In fact, it can set a great example of what not to do for those kids who may be borderline on committing to the summer work.
I've found that kids who slack one summer are more willing to do the summer work on their own accord and not because I as the coach am forcing them to do it or else. Some of you seem unwilling to allow a teenager to make a mistake, learn from it, and do better.
That said, there are some kids who can be cancerous to the team and that should be addressed. I don't think there are many coaches who would disagree with that.
The running community is filled with people who complain that the sport doesn't get enough attention. The fan base is too small to get quality coverage. But if you support the turning away of kids from the sport, what do you expect? Shouldn't we be trying to get kids to be lifelong runners and fans of the sport?
