My guess is since there was no Texas State University in existence at the time of the movie they were able to use that name:
History
Authorized by the Texas Legislature in 1899, Southwest Texas State Normal School opened its doors in 1903. Over the years, the Legislature broadened the institution's scope and changed its name, in succession, to Southwest Texas State Normal College, Southwest Texas State Teachers College, Southwest Texas State College, Southwest Texas State University, and in 2003 to Texas State University. Each name reflects the university's growth from a small teacher preparation institution to a major, multipurpose university. Texas State's original mission was to prepare Texas public school teachers. It became renowned for carrying out this mission, but today it does far more.
Also, we better bring the wood against these other Bobcats as most prognosticators have them in the rear of the Sun Belt:
