Holliday, a 5-foot-5 running back, scored first on a 67-yard pass from Ryan Perrilloux, a Jackson State senior quarterback, with 10:46 left in the third quarter. Holliday's second trip to the end zone came about 5 minutes later on a 2-yard run.
Holliday, who is known more for his speed than his size, totaled 209 all-purpose yards, including 71 on four punt returns, to earn offensive player of the game honors.
"I knew that no one could catch me once I get a step off," Holliday said.
The NFL hopeful, who has so far foregone what looks to be a lucrative professional track career, said he wants "to give this football thing a go" before dedicating himself full time to track.
After a scoreless first quarter, UTEP cornerback Cornelius Brown gave Texas a 10-0 lead with a 35-yard touchdown return off a fumble recovery with about 9:40 left in the first half.
"I wanted to give the fans something to cheer about before this game and I did," said Brown, who was selected the game's most valuable player. "It rolled right back to me and I saw green and took off."
The fourth annual all-star game drew 26,041 fans.
Kenny Hansmire, the game's CEO, said he expected a larger crowd -- about 42,000 people showed up in 2009 -- and would not look at moving the game to San Antonio or Dallas.
