"The linebacker -- I think Jamie Collins flashed some things in the first preseason game where he's coming back (from injury). He's had a really nice camp so far," Dorsey said. "I think the growth of Myles Garrett will be very important. I can't wait to see him. I can't wait to see more reps out of (safety) Jabrill Peppers. The acquisition of (safety) Damarious Randall -- I think that was very important. It fits the true free safety model that helps Gregg Williams' defense roll. I like the way that the young guys have stepped up and played in terms of the draft picks, and I like the competitiveness of the positional battles going on right now."
