Southwestern University: (A)* Southwestern University (SWU), a large state college in Stephenville, Texas, 30 miles southwest of the Dallas/Fort Worth metroplex, enrolls close to 20,000 students. In a typical town-gown relationship, the school is a dominant force in the small city, with more students during fall and spring than permanent residents.

To bolster its chances of reaching the elusive and long-desired number-one ranking, in 2009, SWU hired the leg- endary Phil Flamm as its head coach.
