"It feels great. All that hard work paid off for me."
Dauphine, who is currently a junior, ran a personal best 20.76 to win the state title. He also placed fourth in the 4X100 meter relay.
The Port Arthur Memorial speed racer went into his race with some motivation.
"I felt like I had to prove a point that I was the fastest kid."
Although Dauphine is a state champion in track, he is solely focused on playing football in college.
"When I get to Texas Tech, I'm really just going to be concentrating on football."
