Brandon Williams already has flashed the speed.
Now, the Brookshire Royal (Texas) running back wants to show he has power, too.
The 6-foot-1, 188-pound Oklahoma commitment topped 1,800 yards rushing and 500 yards receiving as a junior, then he won the 200-meter dash at the state track championships in the spring. Brookshire Royal coach Marshall Green said Williams spent much of his summer lifting weights, to add power to his speed.
Williams was committed to Baylor but soured after a campus visit and instead chose Oklahoma, the school of his boyhood idol, Adrian Peterson. Green said Williams has the potential to blossom into a back like Peterson, now an All-Pro with the Minnesota Vikings.
"He runs hard, he has power and he has breakaway speed," Green said. "You can see a resemblance."
Green said Williams joins coaches in meetings to break down game video, helping him develop a strong understanding of the game to go with his physical skills.
"Every day, you hear him say that he's learned something new," Green said. "He's learning how to read defenses, he's learning how to pick up blitzes, how to run screens correctly. And whatever he's lacking, he's willing to learn how to do it, so that he's not lacking in it anymore."
Green said Williams is hoping to graduate from high school early and practice with the Sooners next spring.
