I agree about frat's inability to show up on time. When I was at Tech, I was in a frat and was never late for a home football game. However, our block would rarely fill up before the start of the 2nd quarter. Frats use football games as a party/social event, so instead of watching the game they use the first quarter to down a few more drinks, which is a tradition I really wish we could change to mimic such schools as Virginia Tech which is packed as their team runs out of the tunnel. Frats are a major factor, however, in providing the atmosphere or the 12th man if you will. When the frats really get into the game, the house will be rockin. I've sat in most parts of Bobby Dodd stadium and no where was as loud as the front row of the North Stands with the frats yelling at my back. That's where I sat when Notre Dame came to town and it was absolutely deafening.
There is definitely a flaw in the Block Seating system which results in some students not getting tickets to big games. The reason the Block seating system works and is utilized is consistency. Frats show up and support Tech football more consistenly than any other organization outside of swarm. DRad knows he wants atmosphere at the football games, so the last thing he wants to do is keep frat guys from sitting next to fellow fraternity members and raising hell. I do not condone the swearing and chunking stuff on the field that some fraternity members think is a part of their gameday experience, but they are an important part of the game/crowd.
If you are not in an organization and are forced to miss a game because you didn't get a ticket, then I honestly hate it for you, but tough sh*t really. Join swarm. Don't stand outside the stadium holding up a sign that says "Dan Radakovich stole my ticket" like a coward. Pay the $20 and join a club that takes advantage of the block seating. If you're too cheap to pay $20 to ensure you get your season tickets then don't cry to me when you watch the biggest game of the year from the dorm room.
