Your memory of 1990 isn't entirely accurate. After the ball got rolling that year, by the end of September, attendance was at or near capacity. The stadium was purported to hold 46,000 at the time, but later (after capacity was increased to 55,000) GT officials admitted it had only held around 43,000. I don't know how they crammed 46,000 in for Clemson and South Carolina, but according to the official figures, they did. The crowd in attendance for the VT game might have been disappointing, but ticket sales were very near capacity.
Winning sporadically won't pack the house, but winning
consistently will. What won't work is wasting a lot of money adding distractions and frills to the game experience and jacking ticket prices out of sight in an attempt to pay for them. At some point, if we start packing the house we have, then would be the time to start considering adding to it. The only money we should be considering spending on the stadium at this point is maybe chairbacks, IMO. And I could take them or leave them. All I ask is a winner on the field.
