Well there is two possible reasons why Discipline is so passionate about my tactics. He probably just wants to here me say, "yea, you're right, I was over-confident." However, my favorite logical reason behind his passion is that he is a huge fanatic of Ambitious and Misunderstood. Therefore he is so upset that the coach ruined Discipline's chances to see his favorite team (Ambitious and Misunderstood) to make it to the finals.
Regardless, my move against Albany was fairly ambitious, and I don't need anybody to understand that... excluding TP, you can understand it.
