Lance Brooks was a Sunnydale High student and the older brother of R.J. Brooks.
Lance told Xander that before R.J. joined the football team, he was really into "geek stuff" like comic books and Model UN, suggesting that he was more intelligent than he appeared. He also enjoyed writing poetry, showing a more sensitive side. The implication was that after getting his enchanted jacket, the women constantly fawning over him changed him from "geek" to "jock". Even then, he expressed some respect for one of his old English teachers.

You might not know it now, looking at me with a couple extra pounds, but back then I was quite the guy.
