Exactly. That's part of the whole deal. I think ours will be 2nd in the country by only 100 square feet or so, which isn't all that noticeable when you get to that size. When you do yours, likely next year, it'll be slightly larger. To the untrained eye, they'll look exactly the same, but you'll get to claim having a larger one by a little bit. That's the way these things work.
And the next time LSU, Florida, Alabama, or another money school puts up a new jumbotron, it'll be a few square feet larger than Texas's.
