1st post, so i'll try to make it a good one. they'll all go downhill from here....
here are two recent examples of teams taking DT in the 1st Round in consecutive drafts which seem to have worked pretty well for them.
New England
2004 Vince Wilfork #21 overall
2003 Ty Warren #13 overall
and for good measure
2001 Richard Seymour #6 overall
Jacksonville
2002 John Henderson #9 overall
2001 Marcus Stroud #13 overall
2006 Team DEF Rankings
Overall
Jacksonville #2
New England #6
Against Run
Jacksonville #4
New England #5
true, in the case of New England, Seymour and Warren are now DE's, but they were drafted as DT and converted later. seems like building the DL has worked pretty well for these two teams.
