Stoops: Peterson to Start Saturday Courtesy: SoonerSports.com NORMAN, Okla. -- Oklahoma head coach Bob Stoops said Tuesday that true freshman Adrian Peterson will start at running back this Saturday when the Sooners host Texas Tech. Peterson ranks ninth nationally with 133.3 yards per game (6.2 per carry). Peterson is the first freshman in Oklahoma history to rush for 100 yards in each of his first three game games. One other Sooner reached 100 yards in his first three games. That was quarterback Steve Davis, a sophomore at the time, who achieved the feat in the first three games of 1974.
