At least according to this analysis by Pro Football Focus. The blog post takes a look at who catches the most deep passes (i.e. passes thrown at least 20 yards in the air), who gets the most yards on them, who catches the highest percentage of those targeted to him and more. While Armstrong isn't in the Top 10 in deep pass targets or deep pass catches, he does rank in the top 10 in catch percentage (tied for 10th) and yards on deep passes (sixth).
↵The article notes Armstrong's inclusion at the bottom.

↵↵↵I'm not talking about the Mike Wallace's and DeSean Jacksons' - you already know about them - but about just how devastating a player Kenny Britt can be if he doesn't let off field issues consume him, or how Redskin Anthony Armstrong is able to pick up so much yardage on deep routes.

Granted, Armstrong caught a lot of deep passes last year because he was the deep threat, but it's still an interesting set of numbers.
