I will say that it is easy to confuse jingoism with patriotism. For what it's worth, I was close friends with her when I was younger, and she has always been passionate about that school. As a student, in addition to being an outstanding student, she was a great ambassador for the school. Hell, if memory serves me correct, she may have even been a cheerleader/mascot.
Now she is the principal, and I cannot imagine someone being more passionate about their school as an administrator than Nichole (Dr. Bourgeois).
Now I don't know anything about the coach from Live Oak, but if she thought that her school was at a disadvantage because of some rule which stated that you had to clear a field a certain amount of time before a game, you bet your arse she would do what she needed to give her school an advantage or prevent a disadvantage.
Some may refer to her as a c-word, but I assure you, she would lay down in traffic for that school and those students. If she was your principal or your child's principal, you may not condone having an opposing coach handcuffed, but you'd have to admit that it would get your football team ready to play some football.
