If watching or caring about Tech football is making someone unhappy to the point that they genuinely, sincerely want to quit caring about it, then they should. Everyone cares for different reasons, and if you find yourself personally miserable as the result of the team sucking, it is probably a good idea to at least step away. It is better, I think, than being one more miserable bastard repeating their displeasure over and over again on the internet.
And there is nothing wrong with coming back when you feel like it will be a better experience for you, nor does it make you fairweather fan or a bandwagoner. Especially for the people who have been around for decades, there have been more than ample opportunities to abandon ship, but maybe none quite as immediately bleak as this one. And eventually the team will be better again. I don't buy into the notion that we're watching the "death" of Tech football in any sense other than the demise of the apparent dream we seem to have been sold by Collins, and the safe bet that we are most probably going to suck for as long as it takes for him to be fired and the next guy to "rebuild", whatever the öööö that means anymore.
It is what it is. Take care of yourself, Tech isn't going anywhere that you won't be able to catch up to it.
