"Some of it looked like football," Riley said Friday at his first Big Ten media days. "Not totally yet. But some of it looked like football. So we've got a long way to go in that."

"So we've had to do a lot of studying and being specific about what that really is and how that looks. And so we kind of dove into some of that stuff in spring practice and will continue with it," Riley said. "And at the same time, we wanted to be selective about what we've done and done well in our past that would fit the skill set of the people that we have here."
