I would argue no. The shotgun draft approach isn't just about building depth, it's means you have more raffle tickets that could turn into Russell Wilson's and Richard Sherman's. You draft a guy like EJ Wilson, Mark LeGree, or Korey Toomer and he doesn't even make the team, it's an acceptable form of waste. If Seattle hadn't wasted a pick on Kris Durham in the 4th round, maybe they are drafting him in the 5th round instead of Sherman. It's kind of a domino effect. More bullets fired equals more hits.
This year Seattle already has 8 to 10 picks. Given the quality of the roster you can probably expect 3 or 4 players to not make the roster out of the draft, but you could also expect that 2 or 3 of them will be terrific players.
Now, if Seattle feels that some area is an urgent need, and trading up is the only way to address it, then that changes things. For example, if they felt they needed another pass rusher to replace Clemons, they would probably need to move up and grab Bjoern Werner (which is a move I'd be a fan of, it'd be a lot like when Green Bay moved up for Clay Matthews).
