Most of these athletes have been playing football, or another sport, since elementary school. By now, they know the rules and should be disciplined players. The Corey Flagg comments says more about the players than coaches. Why are players needing to taught or coached in practice self discipline or self control? Self discipline is one of the basics of any sportlearned during youth football, basketball, soccer, tennis, swimming, etc. Sure self discipline should be addressed and emphasized during practice. Blame coaches for play calling, game planning, preparation, communication, knowledge of rules, etc. If players were too "hyped"or "shook", etc., (which could happen in this rivalry game) more experienced players should have stepped in and calmed players nerves. Undisciplined penalties, 90% of that responsibility is on players. Just my opinion.
