The Rams' offense exists, in theory. But who wants talk about our new injury-prone quarterback (Nick Foles, anyone?) when the defense features the reigning Defensive Rookie of the Year, Aaron Donald? Not us, that's for sure. And if we were an NFL quarterback, we'd sure as hell be worried about Donald's terrifying speed. A defensive tackle listed at six-one and 285 pounds, Donald moves like a quick-footed wrecking ball, blowing past offensive linemen and surprising QBs in the backfield. Considering the season Donald put together last year (nine sacks — a Rams rookie record), there's no telling what we'll see from this 24-year-old in 2015. That should make the rest of the league very, very nervous.
