In the end, a high school coach's "product" is not so much the wins, or the championships -- both easily measured by even the narrowest of thinkers -- but the positive impact and example he or she sets for a community, a school, a sport, a team, and ultimately the young people he or she coaches.
I suspect that, if you asked any one of the coaches who post here, they'd tell you that their best coaching doesn't yield championships, but rather, champions.
