Defensive scheme to blame for lack of pass rushing?

[*ochocincos*]

When seeing the team have such a lack of production with rushing the passer including Carlos Dunlap, I was interested to see how Dunlap would do now that he's at SEA.

I saw Joe Goodberry tweet the following about Carlos Dunlap:

Carlos Dunlap has already rushed the passer 104 times with Seattle. PFF has awarded him with 13 pressures and 5 sacks.

Dunlap rushed the passer 186 with Cincinnati. He had 13 pressures and 1 sack during that time.

He's now back on track to have his typical statistical season.

When looking at pro-football-reference, I see similar trends:
Dunlap with Bengals:
7 games, 7 pressures, 1.0 sack

Dunlap with Seahawks:
3 games, 4 pressures, 3.5 sacks

So Dunlap is being used solely as a pass rusher in Seattle but was asked to only rush the passer part of the time in Cincinnati.

This leads me to believe that part of the problem for such bad pass rush is because of how the players are being used, not so much because the players are not good at it.
