My son has played for Mark for four years. Is he tough? Yes. Is he demanding? Yes. 90% of our players have been with him for that long and my son, for one, will give him 100% credit for his evolution into a very good player. If it were the misery slog that outsiders describe, kids would leave but they don't because they love playing with each other and they really enjoy the results of their hard work. I'm sure true for players on Hawks, Madlax etc... where I think there are a lot of outsiders looking in and making absurd criticisms.
