Institutions like laying claim to monikers in college football. Each revolves around a tradition of some sort, but the identities are embedded deep within a program's soul and fabric. They transcend time and endure beyond the ups and downs of normal recruiting cycles, as if they are immortal, living beasts constantly fed by another name over the passage of time.
Every school has something it claims. Boston College, for example, is "O-Line U" because of the linemen sent to the NFL over decades' worth of time. Miami has the renegades and the Turnover Chain. The entire SEC is defined by the motto that "it just means more," and football is tradition for the schools in Texas and the American southwest.
