Aaron Donald finished the 2017 season with 11 sacks in just 14 games, once again proving he might just be the single most dominant player in the NFL. The fact that he led the NFL with 91 pressures from the interior adds to that sentiment.

He closed out the year with an overall grade of 99.7 from Pro Football Focus, 0.2 shy of a perfect grade. That’s eye-popping, to say the least. Not only was that the highest of any player at his position, but it was the best in all of football.

His best game came at the most crucial time, too. In the Rams’ Divisional Round loss to the Atlanta Falcons, Donald had a game grade of 98.6, which was No. 1 among all interior defenders last season.

Donald dominated the Falcons’ interior offensive line from the start, as he totaled 10 of his 11 pressures through the first 30 minutes of play, tying Houston Texans’ J.J. Watt for the most first half pressures recorded in a single game in the PFF era (2006-2017). Adding to his feat, Donald needed just 20 pass-rush snaps to pick up 10 total pressures, while Watt did so on 30 pass-rush snaps in 2014.

Despite moving to a new position, Donald was the same dominant player he had been in the Rams’ previous 4-3 defensive front. Players his size that play his position aren’t supposed to generate as much pressure or record as many sacks as he does.

As far as game grades go, the next-closest player was Kenny Clark at 95.1 in Week 6 against the Vikings. Donald, unsurprisingly, had three of the five-best games by interior defenders in 2017.
