He’s done both, his year at Oklahoma State produced 350 in the air, 180 on the ground. With a 1500 yard rusher. He was one of the first to break out the diamond formation in the pistol, and added a lot of motion and jet sweep from the conventional air raid.
At WVU he played to his strengths that he had, in 2016 he ran 58% of the time. He consistently has evolved his approach.
With all that said, his Houston tenure was pretty disappointing, and his offense was a big part of that. They were held to 28 or under in 7 of 9 Big 12 games this year.
