What are everyone's thoughts on our D Line this year?

IMO, the interior line with Togiai, Haskel Garrett, Vincent, etc. has been fantastic.  Great at clogging the middle, stopping the run and collapsing the pocket on many passing plays.

The DE's have been pretty disappointing.  I was hoping that Harrison would really step up in his 2nd season and that 12th year red shirt senior Cooper would as well.  So far they aren't getting many sacks and they have been losing outside contain too often on wide running plays as well.  Smith has been solid but overall the DE's have been disappointing IMO.  Maybe I have just been spoiled with 6 years of Bosas and 3 years of Chase Young.

What do you say?
