Assuming the coaches actually trust Williams, I think he is a full time DE. Certainly between Lawrence, Armstrong, and Williams you can give Parsons some breathers from playing DE. They don't all have to be stellar pass rushers. Sometimes you're going to be in down and distances where you want more of a run stopping look. Any obvious passing situations I don't care who you add at DE, you're going to want Parsons out there rushing the passer.
Ultimately, I think you're talking about marginal improvements by adding another DE in the first few rounds. What you need to focus more on in my opinion is positions that could have a greater impact. DT, OG, WR or even TE. Positions where if you hit you get more than a marginal impact. You get someone that can change things dramatically on their side of the ball. Hell I'd even say LBer and CB would have the potential for a bigger impact. Although with Bland, Lewis and Diggs I kind of wonder if whatever corner we draft won't end up in a similar situation to DE, where we are just trying to use them for spot duty or to rest guys.
Or you're looking at a DE who you think is or can be special and is just too good to pass up. Maybe that's a Nolan Smith, I don't know. I'm leary of any guy who has such limited snaps and numbers as him but that's sort of the problem with most Georgia guys. Certainly that didn't translate well immediately for Walker or Jordan Davis so we will have to see. Or even Nakobe Dean who was supposed to be this stellar prospect. Maybe Georgia guys are just overhyped or the heavy rotation makes them look better than they actually are because it's easy to put your best foot forward playing only every few plays.
