Not even winning NFL Defensive Rookie of the Year can satisfy Aaron Donald.

Entering his second year, Donald is as hungry as ever to improve upon Year 1.

It's evident to defensive coordinator Gregg Williams, who, on this day, sees Donald watching game film an hour before position meetings begin.

"I'm not going to change what I've been doing," Donald said, via the team website. "That's why I've had success. I'm not comfortable yet so I'm not going to stop doing any of the things that helped me become player I am."

It's a scary thought for opponents come fall.

But the Rams are more than happy to see what Donald has in store for an encore.
