The win was Texas' first of the Tom Herman era, as the Longhorns' overall depth, size and talent overwhelmed San Jose State. Texas outgained San Jose State 623-171 and had six rushing touchdowns.
The Longhorns (1-1) struggled early on but used its rushing attack -- and namely sophomore Warren III and third-string quarterback Jerrod Heard -- to take control of the game with three touchdowns in the first half.
Heard, who has worked mostly as a wide receiver this season, ran 9 yards for Texas' first touchdown at the 2:56 mark of the first quarter as the Longhorns forged a 7-0 lead.
Warren then ran 41 yards for a score 2:12 into the second quarter to push Texas' advantage to 14-0. Heard added to the lead with a 3-yard TD run with 16 seconds to play before halftime as the Longhorns built a 21-point cushion at intermission.
True freshman Sam Ehlinger (15-of-27 passing for 222 yards a one TD) got the start for the Longhorns in favor of sophomore Shane Buechele, who bruised his throwing shoulder last week in Texas' 51-41 loss to Maryland and was ruled out of the game about 30 minutes before kickoff.
Montel Aaron led the Spartans (1-2) with 104 yards passing.
Texas outgained San Jose State 310 yards to 100 in the first half, including a 186-38 advantage on the ground, and owned a 19:48-10:12 edge in time of possession before halftime.
The Longhorns kept their foot to the pedal in the third quarter, driving 92 yards in 16 plays to a Kyle Porter 3-yard TD run that extended their lead to 28-0. Texas held the ball for 6:35 of the quarter during the march, which featured 12 runs and two short completions.
Texas' defense also got in on the fun, scoring on a 45-yard Holton Hill interception return with 48 seconds remaining in the third quarter. It was Hill's third TD this season on a return (he had touchdowns after an interception and a blocked field goal in the opener against Maryland). Texas had no defensive or special teams score in the 2016 campaign.
Warren added his second touchdown of the game early in the fourth quarter, carrying a defender and guard Patrick Hudson into the end zone on a 9-yard TD run.
