Many players have worn the number 7 jersey for the University of Texas Longhorns throughout the years. There's no single definitive answer without specifying the sport and timeframe. To answer your question accurately, I need more information. For example, are you interested in:
* Football? If so, what year or era?
* Basketball? Again, specifying a year or era would help.
* Another sport? Please specify.
Once you provide more details, I can give you a more precise answer.
