Early 40s here, and I've been watching Vols games since elementary school. Been attending home games (along with some away games and bowls) since 2011. With each year that has passed, I've gotten to the point where the game outcome (positive or negative) doesn't affect me all that much. I see the game as just that: a game...it's entertainment. Tailgating at home games is by far the highlight of the day, along with the P.O.T.S.
The days of letting the outcome (win or lose) of a game played by a bunch of random young adults affect me have faded. If the Vols find a way to win, cool. If they lose, bummer. Life goes on.
I don't see any reason to throw any additional financial (beyond ticket purchases and getting to the games) or emotional capital (beyond generating a reasonable amount of noise at appropriate times) at a team of paid mercenaries, which is what the sport has become. If others care to do so, that's obviously their own prerogative as it is mine to decline to do so. In the big picture, it's just not that important to me anymore, and that importance is fading year by year as the game's metamorphosis continues.
