Carnahan's sophomore year, Hereford went 13-2 and lost in the Class 4A Division I state finals. He only started three football games during his junior season.
During his senior campaign, Carnahan was a Class 5A-4A All-South Plains choice by The Avalanche-Journal, logging 35 pancake blocks and a 96-percent blocking grade for Hereford, which finished 8-3 this season.
He scored 23 on the ACT and 1,120 on the SAT. He carries a 4.0 grade-point average on a weighted scale.
Thayer's Take: "Andrew provides excellent pass-blocking and pulls off the ball well. He's very mobile for his size and finishes his blocks with authority. He played in a pass-oriented scheme in high school, which should ease his transition to Tech's wide-open aerial attack."
