You are so right. Why would he get up and tell a player any extra tactics during a game. Why advise one of the young players where they might be going wrong or move players positions or show any pashun for his employers. If I went to work and told people who work for me the plan at the beginning of the day and then never spoke to anyone again to advise or point out something during the working day because things had changed, until we finished and went home, I think I'd be looking for new employment.
Looking to defend him beggars belief.
