Yeah, Vince Wilfork was hardly a presence out there on Sunday.

That's the 2010 draft class. Whom would you have preferred to have that was available? Jerry Hughes? Jahvid Best? The need for a legitimate NT was dire, and you only really get dominant NTs in the first couple of rounds of the draft.
I have absolutely no problem drafting Dan Williams.
Wilfork plays on passing downs, Dan Williams doesn't. Hell, give me Sean Lee in the first and Daryl Washington in the 2nd and we are set at ILB for the near future.
NT are a dying breed in the NFL these days, unless they are versatile enough to rush the passer.
Here are the 3-4 NT's in the NFL
NY Jets - Sione Pouha, 3rd rnd, 2005
Pittsburgh - Casey Hampton, 1st rnd, 2001
Houston - Shaun Cody, 2nd rnd, 2005 (by Detroit)
Indy - Antonio Johnson, 5th rnd, 2007 (Tennessee)
KC - Dontari Poe, 1st rnd, 2012
San Diego - Antonio Garay, 6th rnd 2003 (Cleveland / Aubrayo Franklin, 5th rnd 2003, (by Baltimore)
Green Bay - BJ Raji, 1st rnd, 2009
Washington - Barry Cofield, 4th rnd, 2006 (New York Giants)
Dallas - Jay Ratliff, 7th rnd, 2005
San Fran - Issac Sopoaga, 4th rnd, 2004
Baltimore - Maake Kemoeatu, undrafted
Arizona - Dan Williams, 1st rnd, 2010
New England lists as a 4-3, but I would give you Wilfork if you wanted. With New England, there are 13 3-4 teams in the NFL. 5 of those teams have used 1st round picks on NTs which totals just under 39%. In two games in 2012, there are 5 3-4 teams in the top 10 in the NFL vs. the run. Of those teams (San Diego, New England, San Francisco, Houston, Washington) only 1 has a NT on it who was drafted in the first round. So, I believe you can find effective NTs in other rounds than the first.
