Dwan was not a NT but a 3 technique guy whose job was to penetrate and get to the quarterback which is exactly what he did quite well. You must be confusing him with Ron Edwards who was the NT. We finally were able to get a push up the middle which is one of the reasons that Hardy was so effective this year. Teams couldn't double him like in the past.
I think I been watching this team for the last decade that I can even tell you who were on the practice squad 5, 8, 10 years ago. I know who's Ron and who's Dwan. I also know that Dwan is our UT and Ron our NT. Im not confusing the two.
You guys are forgetting that we still have to replace 'RON' also, and not just Dwan. What I meant is that we could go a Sione Po'uha and Sheldon Richardson in the draft. Richardson replacing Dwan. He may not find the success Dwan has last season "6 sacks" in 2013, but he should be able to penetrate enough to find stability. That's Richardson's game; creating pressure.
