I think OBD looked at spiller as the same type of player as Jamaal charles and it seems everyone at obd was convinced he was a no brainer. I guess it's difficult to fathom, but not every player starts off great. Since I've been in pittsburgh I'm innundated (sp) with their picks, but many have started slowly. Troy P was being talked about as not worth the pick after his first year; Timmons (1st round) didn't play while Woodley (2nd) started from the beginning; Ziggy Hood didn't play much in his first year either, and hasn't played much until Aaron Smith got hurt. Point being you take the biggest difference maker you can. I'm not saying it will always work out, but I don't think it was a reach to take Spiller at that spot.
Guys taken by Levy/DJ in the first round were all driven by need, Nix makes a statement with Spiller that he's taking the bpa as they see it because he certainly wasn't a need. In the past that could have meant Nix would have considered Ngata even though he wasn't a Tampa 2 DT because maybe they thought he was the best player available. With Levy/DJ if a player didn't match the need he wasn't considered. So there is hope a DE could get taken at #3 even though Nix has brought a couple in already, because he isn't afraid to overdraft a position. So you've got that going for you.
For me, I'm looking at a qb or Miller, with a dark horse of peterson or green. I just don't see the value of a 5 technique at number 3, even if that player can also play the nose. We can get run stoppers later in this draft.
