What’s With Harrison Smith’s PFF Grade?

NFC Defensive Player of the Week honors went to Harrison Smith in the first week of the season after a performance that looked dominant at first glance. Smith notched a game-sealing interception, a fumble recovery, a sack and some gnarly tackles for loss. But he also had some lapses in coverage that San Francisco failed to capitalize on.

Here’s a couple of those spark plays, broken down.

But looking at his grades, he had a 57.7 total grade and a 43.7 in coverage. What gives?

PFF doesn’t give a defender credit when the offense screws up an opportunity they only had because he screwed up himself. Take this play, where Harrison Smith bites really bad on the play action and gives Kyle Jusczcyk a clear path to the end zone. Garoppolo messes up, but PFF will count this exactly the same as if Jusczcyk had caught it and ran in for 6:

If you count this play, the actual touchdown in his coverage and the George Kittle miss broken down below, you could feasibly credit 3 touchdown opportunities to Harrison Smith’s mistakes. It makes sense that PFF would downgrade him and cut into all the good grades from the productive plays.

Statistically, Smith was targeted 6 times (too many for a safety) and gave up two: the 22-yard touchdown and a 10-yard completion on an out pattern with a less-than-stellar tackle.

It should be noted that his 3 run stops is a fantastic number (not sure if the play on Earl Mitchell is counted on that, but it should be regarded just as positively). His PFF run grade (81.8) does reflect that production, and most of PFF’s issues come from the poor coverage scattered across his day.

None of this should worry you too much going forward. There’s a lot of season for Harrison Smith to work these kinks out, or just decide to be a little less greedy. He’s still the all-world safety we know and love, and as the season progresses, he should continue to be a difference-maker.

Thanks for reading!
