Taking it a step further if you look at the Saints OL and the Vikings OL
Saints
LT Jermon Bushrod 4th round (The usual starter has been out all year but Jammal Brown was a 1st round pick)
LG Carl Nicks - 5th round
C Jonathan Goodwin 5th round (originally drafted by NYJ)
RG Jahri Evans 4th round
RT Jon Stinchcomb 2nd round
Vikings
LT Bryant McKinnie 1st round
LG Steve Hutchinson 1st round (signed from Seattle)
C John Sullivan 6th round
RG Anthony Herrera UDFA
RT Phil Loadholt 2nd round
New Orleans ranked 6th in rushing 4th in passing 20 sacks allowed
Minnesota ranked 13th in rushing 8th in passing 34 sacks allowed
Indy ranked 32nd in rushing 2nd in passing 13 sacks allowed
NY Jets ranked 1st in rushing 31st in passing 30 sacks allowed
There is no right way or wrong way (use high draft picks or wait until the middle rounds or sign the top name FA's) and investing 2 or 3 of our first 3 picks does not mean we would be instantly better. Those guys all have equal opportunity to bust as any other prospect no matter how sure a thing we may think they are. I do believe we should look to draft at least 1 OL in the first 3 picks but at the end of the day it's about drafting the best football players for this team regardless of position.
