'"This Preston Brown is going to be a star," said Rob Ryan, officially the Bills' assistant head coach/defense. "He's been fantastic. He's a vocal guy. He is extremely smart. He knows the defense, he knows the in's and out's now. So he's really going to grow in this system and he's got a young player next to him that is like his twin. They love football. They're both tough guys. And they're going to grow together. We're going to have something special here — you watch.'
