I think Raji's nickel snaps have steadily declined over the past three seasons. I believe the article I linked showed that statistic.
Decline yeah but he's still had plenty of opportunities to rush the passer. That's what happens when you aren't that good.
the article said pass rush snaps and I think it's going by PFF in that case (they count .5 sack as 1)
2010 507 pass rushes 7 sack, 4 QB Hit, 24 QB Hurry
2011 548 pass rushes 3 sack, 1 QB Hit, 16 QB Hurry
2012 366 pass rushes 0 sack, 1 QB Hit, 22 QB Hurry
2013 235 pass rushes 0 sack, 3 QB Hit, 08 QB Hurry
The defense had significantly less plays in 2012 than 2011 so there weren't as many opportunities overall but his production was still similar. This year though he has completely fallen off the map and been entirely ineffective lending to the idea that he just isn't trying as hard. Though none of these numbers are that impressive for a guy who is complete crap against the run. This is supposed to be his thing
and at his very best he's average at it.
For reference here is Mike Neal last year (A guy who has never even sniffed a pro bowl vote and is always banged up)
2012 205 pass rushes, 5 sack, 3 QB Hit, 12 QB Hurry
And Daniels this year
2013 278 pass rushes 6 sack, 5 QB Hit, 19 QB Hurry
He's already about equal to Raji's highest production season ever but with just over half the pass rushes. This guy is an undersized 4th round pick. Not an extremely athletically gifted 9th overall 320+ lber
Raji isn't even that impressive at the thing he does best and everything else he does terribly which is why I was super confused with the report that he was offered 8m/year or whatever. I cannot believe that offer is still on the table after the effort he's shown this year though. I sincerely hope this guy walks though more than that I don't think he's earned the snaps he's gotten this year and should be sat on the bench.
Heck lets throw in Datone this year (coaches wont even give him more than 20ish snaps a game because of how he's struggling)
197 pass rushes, 4 sacks, 3 QB hits, 10 QB Hurry
