Healthy, motivated, Cowboys' Lee delivering on father's hopes
"I feel like I have a ton to improve in all areas. When I watch the film, I see more of the negative than the positive. Seriously, when I look back at some of my old film, it makes me cringe, because there's so much I can improve. In the run game I can cover more ground. I can blitz a ton better. I'm just going to keep studying, keep grinding. That's what's great about this game, you always have something to work on."
