First, a hit or a hurry is no guarantee that it negatively affected the other teams ability to gain yards. A hit could come just after a QB threw a TD pass. Heck, Julius Peppers had 2 QB hurries on Kaepernick Monday Night. The result? 2/2 for 80 yards.
Without some sort of actual analysis on how many of those QB hits or hurries resulted in negative plays we cannot determine if Von Miller has made anymore positive Defensive plays than Aldon.
If my assumption is correct and the success count is the number of plays that resulted in a positive outcome for the defense is correct, it shows the true ridiculousness of the article.
Von Miller leads 44 to 37, but he has more snaps, so he has a "success" 6.6% of the time. Aldon has a "success" 6.0% of the time. A lot closer at first glance. But if you look at Von Miller's successes relative to his actual Sacks/Pressures/Hits you'll see his pressure results in a success 72% of the time, where as Aldon's is at 86%.
If I'm misinterpreting that stat, please let me know.
Additionally, if you can provide anything that shows his hits/pressures actually benefited the defense, I'd love to see it.
Personally, I know the only sure fire way to know whether your pressure negatively impacted the offense. It's called a sack. And Aldon seems to have a lot of those...
