Sims had a strong year for the Longhorns, but has really gotten traction late in the NBA pre-draft process. He is an incredible athlete, weighing 250 pounds with 5.5% body fat, and he posted a 44.5-inch max vertical at the Combine. He is a menace on the glass on both ends of the floor, plays with a great motor, and excels down low in the dunker spot and as a rim protector.
