I suspect we haven't heard the entire story either.
When I was at UT before the stadium was expanded there were not enough seats for students. Even buying an expensive "activity pass" did not guarantee a student he would be able to get a ticket.
We were national champions a couple years I was there but in five years I was only able to get tickets to two games, both in the visitors' section from politicians who didn't use their's.
The fraternities would make their pledges stand in line all night with enough activity passes to get tickets for the whole fraternity/sorority.
Could it be that the A&M Corps was doing the same thing? That's not fair to other A&M students who don't have underlings to stand in line for them.
They had the problem at Ohio State where the students were selling their tickets to people because OSU makes sure that any students that want in, get in.
Some enterprising students will sell their tickets for double face value. So now OSU puts the word STUDENT in block letters at the top of the ticket if it is sold to one and then yo have to show ID to get into the stadium with it....
