Expressing opinions are part of life and, fortunately, are protected First Amendment priveleges.  I'm also going to vote for our next President, thereby, expressing my opinion about someone  "much more accomplished" than I.  I don't claim to the the "arbiter" of anything. You may not like my opinions.  That's fine, it's the exercise of your right to express YOUR opinion.

Here's the definition for you: [ahr-bi-ter]  1. a person empowered to decide matters at issue; judge; umpire. 2. a person who has the sole or absolute power of judging or determining.

I, indeed, feel Coach K's actions were unprofessional.  That's my opinion.  BTW: I also commented that, if he had problems with Brooks' behavior, he should have had a private word with Coach Altman.....that would have been professional.  You might want to read Coach Altman's comments on this very issue.  They're in this morning's RG.  If you can't find them, let me know.  I'll be happy to help you out.
