I saw that too. He's obviously thinking about ball security, he just needs to get to the point where changing hands is automatic, and not a conscious decision.
The second fumble is less excusable. He had kept on an option and even after the pitchman was out of the play, he was still carrying it like he was about to pitch. Once he decides to go, he's got to just tuck the ball away. Hopefully he sees it on film and corrects it.
Do you guys see his one scramble in the third, after his two fumbles, where once he saw a Fresno player close in on him, he covered up the ball with two hands? He looked like a fullback running the ball.
Nebraska Fullbacks cant even block let alone run with the ball.
