A Big fish in a small bowl will not continue to grow. They are not challenged constantly. They will never reach their full potential. This perspective is what drives teams/clubs to sandbag in leagues and tournaments. Only concerned with W's and L's, and not pitting yourself against the best teams you possibly can week after week. Steel sharpens Steel. This has been proven in many studies evaluating Sports Performance Cusp Theory. Players develop most efficiently and effectively when challenged in an environment that demandt 100% of their abilities, but only finds success 50-60% of the time. If your team is winning more that 80% of the time, they need to move up to a more challenging League/Bracket/Organization. As others have already stated, challenging yourself by playing in the ECNL SW is about prioritizing the players development in the most challenging environment available; building Learned Industriousness, so they don't become overwhelmed or get crushed when they get to college (the big lake). If your primary concern is the win-loss record, sure, find a good team in a league full of mediocre teams, and continue to build the players Ego with all the sandbags. The problem is Sandbag foundations don't last in challenging environments.
