I think a nice brick pattern would work fine. Blend in with the rest of campus.
I love this idea -- for the end zones only. If we wanted to be edgy, we could paint it like it is a graffiti wall.
It would definitely make us more unique. I have always liked the endzones that use something different.
Tennessee's checkerboard is probably my favorite. They may not have invented it but I think there's is best known.
What are some others that everyone is familiar with?
