IMO if we really want him and he is the main target in the draft, dont screw around and just take him at #3.
Heh heh heh. There we go again - trading down to draft for need.
Here's a thing about NT's - They need to be big, dominant and have a non-stop motor. They do not need to be blessed with stopwatch speed, great hands or great field-vision. As such, I'd argue that a nose tackle like Sopoaga in Round 3 is only slightly less likely to succeed as would Wilfork because he's nearly as big, probably stronger, have a better motor and represent no more or less of a risk.
Not so with other positions - like WR, QB, DE or CB - which call for more athleticism. The drop off between the elite guys and the next echelons further down is, in my opinion, much greater because they can't run as fast, aren't as big, can't throw as well, don't hit as hard etc. Therefore, when you can get a really talented prospect, you'd better leap on him when you have the chance.
Here's the problem. Wilfork definitely fills a Cardinal need. And, if he fulfills his potential, could be an animal in the middle for ten years. BUT he's a got a couple of big IFs - (1) historically, he's always run out of gas rather quickly and (2) he quite possibly could out-eat Andrews and beat out the new candidate for "10th planet in the solar system.
In the bigger scheme of things - where the Cards have the opportunity to either (a) land a franchise QB, (b) install a marquis receiver opposite Boldin or (c) land what many call the best defensive player in the draft (and the equal of Roy Williams) - the Cards could pass on Wilfork and, by drafting Sopoaga (say at the top of the 3rd round) do at least nearly as good.
