"I think the thing is to really be able to spend time on the concepts of football that are important to us and breaking things down – offense, defense, special teams. It might be 5-on-5, 4-on-4 type things. Really for the coaches to emphasize those and break down the gray area. Without pads you are unable to be physical and those things so it is more of the mental stuff. It’s important to do that and work on some of the things that we think were important after the season last year for guys to work on and improve. It gets the young guys incorporated in better and some of the new guys like James (Harrison) on defense."

"I’ve been impressed with how they are studying and working hard. When they mess up, you can tell it hurts them and they don’t want to do it again," Gruden said. "Those two guys are focused on what they can bring to the team and they are going to be very good players."
