Taylor was named to the Big 12 All-Newcomer Team and was an All-Big 12 Honorable Mention as a freshman.  He finished second on the team in scoring with 12.7 points per game and led the Longhorns in minutes played (30.1 per game) and assists (4.0 per game). He earned Big 12 Rookie of the Week honors on February 3, 2014 after scoring 23 points in a home victory over Kansas.  In the Round of 32 of the 2014 NCAA Tournament, Taylor scored 22 points on 8-for-22 shooting in a loss to Michigan. 
As a sophomore, Taylor posted averages of 13.1 points and 4.6 assists per game in 24 games, shooting 28 percent from behind the 3-point arc and 52 percent on layups.  He was named to the All-Big 12 Third Team.  He missed several games after sustaining a wrist injury against Iowa in the 2K Classic. With Taylor out of the lineup, Texas struggled, even when he made a return to the team. After the season, Taylor announced he would return for his junior campaign, forgoing a possible second round pick in the 2015 NBA Draft. CBSSports.com's Sam Vecenie wrote that new Texas coach Shaka Smart's "system will accentuate Taylor's quickness and athleticism quite well."
