I have only been to a couple of games in the past 10 years or so. I don't like the dancing, the music, the "everybody clap your hands", the flying t-shirts, etc. HOWEVER, I really couldn't care less. The blessed memories of the sweltering, dirty, smelly, rat-infested Gahden of my youth, have a nostalgic and proud feel now... I was nowhere near the germophobe then that I am now, but even then (70's and 80's) I remember being grossed out by the Garden. In hindsight, it was wonderful; in reality, it was old and filthy.
But the biggest difference between now and the old days is the fact that every game is now on cable TV, every game has a cblog game thread, every game has an NBA.com stat-tracker... It's way better to watch at home than to go to the game (for me), and if it were still as smelly, dirty, sweltering (in May/June) and rat-infested as it used to be, I'd be even more glad to be home.
Today's Celtic's brass has had to deal with an entirely different set of circumstances than the Auerback era. They've adjusted fine and Randy should relax.
Change isn't always good, but it is life's only certainty.
