That is probably why Coples' numbers are better than full time starters like Dockett, Campbell, and Ngata. Coples has played more on obvious passing downs (especially earlier in the year) which will help his stats.
BTW, I think PFF is crap, but that is another discussion for another day.

I'm a proponent of Pffs raw data but I'm not a big fan of prp for two reasons. The main reason is because they dramatically overestimate the impact of a pressure on the outcome of a play. If you sack a qb the play is never successful. The odds go fromabout 35% failure to 100%. Under pressure it goes from 35% to something like 55%. There is no real logic that I can find in saying its 75% as productive as a sack. To me that's a number for agents to try to pump up their client.
The second is what you are pointing out which is the fact that a 2nd and 5 quick swing pass makes the pass rush a non-factor. That why most of the most efficient rushers are not three down players. Admittedly I don't know how you can value that numerically since we don't have down by down data per player to credit them properly but it should always be noted. I think last year Aldon Smith I had rated as most efficient but there is no way you could say he was more effective than Chris Long who played a ton of snaps rather than 3rd and 10. I do actually have the sack rates from last season by down and distance but I don't think anyone tracks it for players.
