Eric Reid 49ers preseasonAs promised, the following are all the defensive stats you won’t find on the box score of the 49ers preseason opener. These are lifted directly from ProFootball Focus’ game charting stats. So, really, all credit belongs there. I’m merely the messenger.

I found snap counts particularly interesting. So, I’ve sorted players at a given position by snap count. As you can see, Tony Jerod-Eddie, Michael Wilhoite and Perrish Cox all lead their respective positions.

Also of interest: Ian Williams did not play nose tackle at all, Cam Johnson earned the worst grade of any defender, Eric Reid is saw a lot action, and Kassim Osgood coupled a strong offensive performance with an even stronger showing on special teams.

Before you go on, an important stat to understand is the “Stop,” which ProFootball Focus (PFF) defines as:

[The] amount of times a defender has caused an offensive failure as a percentage of how many plays he is in on run defense, excluding plays nullified by penalty. An offensive failure (a “stop” from the defense’s perspective) is a play that is unable to obtain 40% of required yardage on first down, 60% of required yardage on second down, or the entire required yardage on third or fourth.
