I understand these numbers don't tell the whole, entire story, but I would expect a starting NFL DE to have higher production than that. I've seen him be a lot more productive when JA was getting double-teamed on the other side, now it's time for him to show he deserves the big contract and the starting position.
He got the "big contract" because he had already earned the starting position and even though you said "forget the sacks for a minute", you still seem to be defining production in statistical terms. If we're going to look at it that way, we should at least find more stats. How often are teams running to his side? How productive are they running to his side? How many QB pressures does he have this season?
I think the sack and tackle stats are far less important than whether a player is performing his role in the defensive scheme correctly. Is Robison anchoring the edge, maintaining his gap and funneling ball-carriers to the LBs? Is he supposed to be making a lot of tackles or is he supposed to be making it possible for the LBs to make a lot of tackles? Is he getting upfield to apply pressure on the QB, making sure the QB is contained in the pocket, etc? Containing the QB and pressuring him into the hands of another defender is still getting the job done, even if a player doesn't earn a sack on a play.
Here's something to think about when assessing Robison's performance:
The Vikings old Cover-2 scheme gave defensive linemen plenty of chances to rush upfield, but Zimmer's scheme mitigates those opportunities with more calls for linemen to engage blockers and collapse the pocket. Defensive ends typically don't accumulate big sack numbers in Zimmer's scheme -- in fact, only two defensive linemen (Geno Atkins and Michael Johnson, both in 2012) posted double-digit sack totals in a season when Zimmer was the defensive coordinator in Cincinnati. Getting the Vikings to grasp the scheme changes has been an ongoing process in Minnesota, and it appears Zimmer isn't fully satisfied with the results yet.
