The Pittsburgh Post-Gazette reports that OC Bruce Arians is blown away by Ben Roethlisberger's play. "It almost scares me how good he is, how into it he is and how good he's going to be," Arians was saying between camp practices yesterday. "It's a night-and-day difference now from where he was two years ago. Then, he was like, 'I've got to take care of myself. This stuff is hard.' Now, he's like, 'I've got most of it down. I can help the other guys.' "
