"You compare first the in-person workout compared to Pro Days. And Pro Days are scripted," Roseman said. "So whatever you're getting from them is something they worked out with either their personal trainer, or their coach, or at the school. When you get to go and work them out individually, they don't know what we're going to ask them to do. So they have to adjust on the fly in that situation. When you bring him in here, you can't do anything on the field. So you're just sitting with them, talking with them, getting a sense of who they are, how they adapt to this atmosphere. It's kind of a different animal."
