Goodness, no you are not the only critic to express their feelings on this forum/board. I feel that you went overboard in your choice of words..."no big loss" in expressing your criticism. The fact that you had to listen to all the critics when your brother played obviously upsets you. But I see no need to use that as a reason for personally "calling out" someone.
Incidentally, I do not believe that anyone "feels good" when an athlete leaves our program. These things happen, and for various reasons. Some of which we will never know.
