It's no secret that Aaron Donald's impact on the field is unmatched.

According to Pro Football Focus, the numbers confirm that notion.

Through two games, Donald has a +18 grade, more than double the best mark any defensive tackle has posted through two games.

In short, he's on pace to "crush the best grade we have ever seen from a defensive interior player."

What's scary is that Donald is even outplaying J.J. Watt at the same point in his career.

Per ESPN: "The highest grade Watt has ever had at this point in a season is a plus-17.3..."

It's been exhausted over and over how great Donald is as a player, and even scarier to think how dominant he can be.

Now it appears the numbers support that claim 100 percent.
