So now, let's break down these players that have already joined the squad.
RB Brandon Williams (6-foot, 190 lb.):
Out goes running back DeMarco Murray and in comes a five-star, No. 3 national running back in Williams from Royal High School.
He's got great explosion with that 4.47 40-yard dash and possesses both power and the ability to blast through the hole by getting down low with his cuts.
Williams had a nice showing at the Under Armour All-American Game and just abused his opponents for more than 2,400 yards and 33 touchdowns, good for an average of 9.8 yards per carry, in his senior season.
A year earlier, he rushed for 1,815 yards and 14 touchdowns, so the guy knows how to get it done.
QB Kendal Thompson (6-foot-2, 180 lb.):
Thompson lives under the legend of his father, Charles Thompson, who wasn't such a bad quarterback himself.
Charles led the then-No. 2 Sooners to a victory over then-No. 1 Nebraska in what was dubbed the Game of the Century Part II at the time.
Now, the time has come for Kendal to make his mark as a Sooner, and he's got a fast start by arriving early.
Kendal also participated in the Under-Armour All-American game, and though he was hurt most of last season with a knee injury, he impressed big time the year before in guiding his Southmoore team to 11 wins and an Oklahoma 6A Semifinal appearance.
A three-star commit, Kendal has both an accurate arm and the ability to tuck it and run with his great mobility.
DT Marquis Anderson (6-foot-3, 260 lb.):
Anderson comes in at No. 44 at his position and ranks as a three-star, but don't be deceived.
This guy is a competitor, quick off the line of scrimmage and routinely commanded double teams in high school.
He led his team at Steele High School in Texas to a State Championship back in December, and he also participated in the U.S. Army All-American Bowl in San Antonio.
He's a talent the Sooners are sure to be happy with.
